    [001] The present invention relates to a fastener, more specifically, in a structure housing an air bag between an automobile body panel and a trim, the fastener being used to attach the trim to a car body structure and extending in a moment of expansion to the air bag so as to form a space between the finish and the structure of the car's body. Fundamental Technique
    [002] In an air bag device for an automobile in which the air bag is housed between the automobile body panel such as a front pillar, a roof panel, and the like, and the trim, there is one in which the panel The car body and the finish are connected using a fastener that deforms (extends) when an act of loading, in order to facilitate the expansion of the air bag by increasing the space between the car body panel and the finish at the time of air bag expansion (eg patent document 1).
    [003] The fastener according to patent document 1 is structured by a cylindrical member engaging a hole formed in the body panel of the automobile; and a column member slidably supported on the cylindrical member, and also engaging the finish at one end. When a predetermined load acts in a direction in which the column member projects from the cylindrical member, the column member projects from the cylindrical member so as to be able to separate the automobile body panel and the trim.
    [004] Furthermore, as another example, there is a known fastener structured by a base part engaging the automobile body panel; a strap-like part provided to protrude from the base part; a wide portion provided on a belt-like portion base end portion; and an expanded front part provided in an end part of the strap-like part (eg patent document 2). In the fastener, at a normal moment, the wide part engages a hole formed in the trim, and fixes the trim to the car body panel, and at the time of air bag expansion, an engagement between the wide part and the trim hole is released, and the belt-like part is pulled from the finish hole until the expanded front part is caught in the finish hole. In this way, the fastener can separate the automobile body panel and the trim only by a length of the strap-like part. Prior Art Document Patent Document Patent Document 1: Japanese Unexamined Application Publication No. 2002-37007 Patent Document 2: Japanese Patent Publication No. 3633537. Summary of the Invention Problems to be Solved by the Invention
    [005] In the fastener according to patent document 1, however, there is a problem that when a load acts in a direction oblique to a geometric axis such as the cylindrical member and the column member, a twist occurs between the cylindrical member and the column member, and the automobile body panel and trim cannot be smoothly separated with respect to a desired load. Furthermore, in the fastener according to patent document 2, due to the release of the engagement between the wide part and the hole of the finish, the automobile body panel and the finish are separated, so there is a problem in which it is difficult to stabilize an amount of load by releasing the hitch. This is because since the fastener and finish are often manufactured in a different location and with a different manufacturing process, it is difficult to match the wide part of the fastener and the finish hole with excellent accuracy.
    [006] The present invention is created in view of the problems mentioned above, and an object of the present invention is to provide a fastener capable of smoothly separating the finish and the automobile body panel with respect to a load in various directions acting on the finish and the automobile body panel in a case in which the desired load acts. That is, the aim of the present invention is to provide a fastener capable of being smoothly displaced even with respect to the load in the direction oblique to a fastener displacement direction. Ways to Solve Problems
    [007] In order to solve the problems mentioned above, the present invention is a fastener (10) that includes a first member (11) engaging a fixed first member (100), and a second member (12) supported on the first member , and also engaging a second attached member (101). The fastener (10) mutually connects both attached members, and also when a load acts in a direction in which both attached members are separated from each other, the fastener (10) allows a mutual separation of both attached members only by one. predetermined distance. The first member comprises a base station (15) engaging the attached first member, a protruding piece part (16) provided to project on the base part, and an expanded front part (17) wider than the formed protruding part part. in an end part of the protruding part part. The second member comprises a through hole (52) in which the protruding part part passes loosely, and a cylindrical part (51) supported on the protruding part part so as to be displaceable. in a projection direction, and also retained from the protruding part part by the base part and the expanded front part. The base part and the cylindrical part are connected by the engagement parts (35 and 64) with release of an engagement with a lesser load than an engagement between the base portion and the first attached member and an engagement between the cylindrical portion and the second member attached. In a state in which the engagement of the engagement parts is released, the cylindrical part has a feature in which a centerline is supported on the protruding part part so as to be able to tilt with respect to the projection direction of the protruding part part.
    [008] According to the present structure, when a predetermined load acts on the first member and the second member, the engagement between the base part and the cylindrical part is released, and the cylindrical part is displaced along the protruding part part . That is, a relative position between the first member and the second member is shifted, and a relative position between the first attached member and the second attached member is shifted. At this time, since the cylindrical part may tilt with respect to the projection direction of the protruding part part, even in a case where a direction of the load acted on the second member tilts with respect to the projected direction of the protruding part part, the second limb can be moved smoothly with respect to the first limb without a twist of the first limb and the second limb.
    [009] Another aspect of the present invention has features in which the through hole includes an elastic piece (54) that can be displaced in a direction orthogonal to a centerline direction of the through hole in a hole wall; the elastic piece including a projection (55) projecting to a central side of the through hole; and the protrusion rests against the expanded front part so as to retain the cylindrical part with respect to the protruding part part.
    [010] According to the present structure, a combination of the first member and the second member can be easily realized with a simple structure.
    [011] Another aspect of the present invention has a feature in which the protruding part part has a flexible property.
    [012] According to the present structure, since the protruding part part may bend, even in the case where the direction of the load acted on the second member inclines with respect to the projection direction of the protruding part part, the second member may be smoothly displaced with respect to the first limb without twisting the first limb and second limb.
    [013] Another aspect of the present invention has a feature in which in a state of being engaged by the engaging parts, the cylindrical part and the base part mutually include a clearance (71 and 72) between the cylindrical part and the base part .
    [014] According to the present structure, since the second member can be displaced with respect to the first member only by a part of the clearance, even in the case where the direction of load on the second member inclines with respect to the direction of projection of the part. of protruding part, twisting between the first member and the second member is prevented, and the engagement between the base part and the cylinder part is smoothly released by a desired load. Effect of the Invention
    [015] According to the structure mentioned above, the first member and the second member are relatively displaced with respect to the desired load, and the fastener can separate a member engaging the first member (e.g., a front pillar) and a member engaging with the second member (eg a finish).

    [027] Hereinafter, with reference to the drawings, the embodiments in which the present invention is applied to a fastener for fixing a finish to an upper part of the front pillar of an automobile will be explained in detail. In a space formed between the top of the front pillar and the trim, an air bag from a side curtain air bag device is housed. When the air bag expands, and a load (an expansion pressure) acts in a direction in which the top of the front pillar and the trim are separated from each other, the modality holder allows for a separation between the part. the top of the front pillar and the trim only by a predetermined distance, and forms a space between the top of the front pillar and the trim. Hereinafter, the fastener according to the modality will be explained on the basis of a geometric coordinate axis illustrated in each figure.
    [028] As illustrated in Figure 1, a fastener 10 according to the modality is structured by a first member 11 and a second member 12. The first member 11 and the second member 12 are respectively molded of a resin material.
    [029] As illustrated in figures 2, 5 and 6, the first member 11 comprises a base part 15, a protruding piece part 16 and an expanded front part 17 as a main frame member. The base part 15 has a hollow box shape, and opens downwards. An outer circumferential portion of a lower end portion of the base portion 15 is chamfered.
    [030] On the right and left side surfaces 22 of the base part 15, there are respectively formed cuts 23 communicating with an inner surface and an outer surface of the base part 15. Each cut 23 has an inverted U-shape that opens to a underside viewed from a right-left direction and forms a cantilevered piece 24 extending upward in a portion interspersed by both sides of the U-shape. Each cantilevered piece 24 bends (elastically) so as to be able to tilt in and out of base part 15.
    [031] In an intermediate part in an up-down direction of each cantilevered part 24, there are respectively formed claw-like parts 25 protruding outwardly from the base part 15. Each claw part 25 comprises an inverted stop surface 26 facing up. Furthermore, in an end portion (an upper end portion) of each cantilevered piece 24, a pressure portion 27 projecting outwardly from the base portion 15 is formed.
    [032] Furthermore, in a part of a front side and a rear side of a part in which the cuts 23 of the right and left side surfaces 22 are formed, the claw parts 31 and 31 are provided to protrude in a position maintaining a predetermined distance upwards from the inverted stop surface 26 of the grip portion 25 in the upward downward direction. Each gripper portion 31 comprises a downwardly facing impulsive stop surface 32. The front and rear side surfaces 34 of the base part 15 comprise convex parts 35 at an upper end thereof and at a central part in the right-to-left direction.
    [033] The protruding part part 16 is formed in a plate shape having a face facing in the right-to-left direction, and is provided to project upwards from the center part in the right-to-left direction of a upper surface 36 of the base part 15. As illustrated in figures 2 and 5, a width (a thickness of the protruding part part 16) in the right to left direction of the protruding part part 16 is obviously formed small with respect to a width in the right-to-left direction of the base part 15, and a width in a front-to-rear direction of the protruding part part 16 is also formed slightly small with respect to a width in the front-rear direction of the base part 15. It is preferable that a width in the right-to-left direction of the protruding piece part 16 is half or less of the width in the right-to-left direction of the base part 15. Furthermore, it is more preferable than the width in the di. The right-to-left portion of the protruding part part 16 is one-fifth or less of the width in the right-to-left direction of the base part 15. The protruding part part 16 is formed as a thin wall so as to have a flexible property and can be bent from left to right. In a base end part of the protruding part part 16, a rib 38 is provided continuing with the upper surface of the base part 15. Furthermore, on the upper surface 36 of the base part 15, a plurality of projecting parts is formed. 39.
    [034] On the right and left side surfaces in an end part of the protruding part part 16, the expanded front part 17 projecting to the left and to the right are respectively formed. Each expanded front portion 17 comprises an inverted stop surface 41 facing downwardly at a lower end, and on an upper portion of the inverted stop surface 41 there are sloping surfaces 42 facing upwardly and to the right and left sides. That is, the expanded front portion 17 is tapered as the expanded front portion 17 runs towards an end of the protruding piece portion 16.
    [035] As illustrated in Figures 3 to 6, the second member 12 comprises a square cylindrical part 51 in which a through hole 52, having a transverse square shape in which a centerline extends in the top-down direction, is formed . On mutually facing right and left side surfaces of the cylindrical part 51, there are respectively formed cuts 53, two by two, communicating externally of the cylinder part 51 and a through hole 52, and also extending in the upward-downward direction, and which upper ends continue to an upper end of the cylindrical portion 51. In a portion secured by two cuts 53 and 53 of each of the right and left side surfaces, there are respectively formed retaining pieces 54 having a cantilever piece shape whose base end continues to the cylindrical portion 51, and also which extends upwardly, and projects more upwardly than the upper end of the cylindrical portion 51. Each retaining piece 54 bends (elastically deformed) as the base end of the lower end portion of so that you can tilt in the direction from right to left. In mutually facing portions near the upper end of each retaining piece 54, there are respectively formed claw portions (projections) 55 projecting towards a center of the through hole 52.
    [036] Each grip part 55 comprises an inverted stop surface 56 facing upwards at an upper part, and comprises a rib 57 continuing to the retaining part 54 at a lower part. The rib 57 forms an inclined surface reaching a projecting end of the claw part 55 from the retaining part 54. While a distance between the projecting ends of each claw part 55 is configured to be greater than the thickness (a width in the right-to-left direction) of the protruding part part 16, the distance between the projecting ends of each grip part 55 is configured to be less than the distance (a width in the right-left direction of the expanded front part 17) between the two protruding ends of the expanded front part 17.
    [037] On the respective upper parts of the right and left side surfaces of the cylindrical part 51, U-shaped collar parts 59 are provided in a flat view bending and extending backwards after projecting to the right-left direction from a front end portion, and thereafter further folding and continuing to a rear end portion of upper portion of the right and left side surfaces. Each collar portion 59 is formed in a U-shape in plan view so as not to block the outward inclination of the cylindrical portion 51 of each retaining piece 54.
    [038] At a lower end of the cylindrical portion 51, a quadrangular flange portion 61 extending outwardly is formed. In an outer circumferential part of the flange part 61, an extended circumferential wall part 62 is provided which extends downwardly along the outer circumferential part of the flange part 61. Furthermore, in the outer circumferential part of the flange part 61, a square circular elastic pressure portion 63 is formed along the outer circumferential portion. The elastic pressure part 63 is a circular member formed in a V-shape such that it can elastically deform. The elastic pressure part 63 works in the same way as a disc spring.
    [039] On a mutually facing front side surface and a rear side surface of the circumferential wall part 62, through holes 64 communicating with the interior and an exterior of the circumferential wall part 62, respectively, are formed. formed in the central part in the right-to-left direction of the front side surface and rear side surface. Eventually, in another embodiment, as a replacement for the through holes 64, pressed parts may be provided on the inner surfaces of the front side surface and back side surface of the circumferential wall part 62. Furthermore, on a right side surface and left side surface facing mutually of the circumferential wall part 62, there are respectively formed notch parts 65 which continue to a lower end of the circumferential wall part 62. In a lower end part of the circumferential wall part 62, a plurality of elastic pieces 66 are formed with a tongue piece shape projecting downward and to an outside of the circumferential wall portion 62.
    [040] The first member 11 and the second member 12 are combined by inserting the end of the protruding part part 16 of the first member 11 into the through hole 52 from an underside of the second member 12. At that time, the part part protrusion 16 is arranged with respect to second member 12 such that a flat portion faces each retaining piece 54. In a process of inserting protruding piece portion 16 into through hole 62, the slanting surfaces 42 of the front portion The expanded part 17 presses the lower parts of the claw portions 55 of the retaining pieces 54 and ribs 57, and while the retaining pieces 54 are being angled to an outer side of the through hole 52, the protruding piece portion 16 is inserted. After the expanded front part 17 passes through between both claw parts 55, due to the elasticity of the retaining pieces 54 themselves, the expanded front part 17 returns to an original position. As illustrated in Figure 6, an insertion of the protruding part part 16 into the through hole 52 is carried out until the projecting parts 39 of the first member 11 abut against a lower end part of the cylindrical part 51 of the second member 12. In this state, two respective convex parts 35 of the first member 11 are fitted in the through holes 64 where the second member 12 corresponds (the convex parts 35 are caught in the through holes 64) and the first member 11 and the second member 12 enter into a state of being mutually locked (engaged). The convex parts 35 are locked in the through holes 64 so that the first member 11 and the second member 12 are held in a state in which the protruding part part 16 projects at most from an upper end of the through hole 52 A state illustrated in Figures 1, 5, and 6 is an initial state of the fastener 10. In that state, the pressing parts 27 enter a state in which they are disposed within the notch parts 65, and the end parts are exposed to an outer surface of fastener 10.
    [041] As illustrated in Figure 5, in the initial state of the fastener 10, in the right-to-left direction, the base part 15 includes a void (a gap) 71 between the base part 15 and the inner surface of the part. of circumferential wall 62, and the protruding piece portion 16 includes a void (gap) 72 between an inner surface of the through hole 52 and the jaw portions 55. In addition, an inner circumferential part of the through hole 64 is large. with respect to an outer circumferential part of the convex parts 35, and the convex parts 35 are in a state in which they are loosely fitted into the through holes 64. Consequently, the first member 11 and the second member 12 are connected to each other with a clearance (an oscillation), and can rotate relatively within a predetermined range as a center of the convex parts 35. Furthermore, even in a case where the sizes of the through holes 64 and convex parts 35 correspond approximately, since the convex parts 35 or the through holes 64 bend slightly, the first member 11 and the second member 12 can rotate relatively within the predetermined range.
    [042] In the initial state of fastener 10, when the first member 11 is fixed, and a predetermined load attaches to the second member 12 in a direction of retraction of the protruding part part 16 from within the through hole 52 (that is, in a direction in which the second member 12 is displaced to one side of the expanded front part 17), the convex parts 35 and the circumferential wall part 62 bend, a locked state between the convex parts 35 and the through holes 64 is released, and the second member 12 is moved to the side of the expanded front part 17. In the initial state, the first member 11 and the second member 12 can rotate relatively only a little like the center of the convex parts 35, so that even if the direction of the load which acts on the second member 12 is slightly oblique with respect to a direction of projection of the protruding part part 16, a twist between the first member 11 and the second member 12 is prevented, and engagements between the convex parts 35 and the through holes es 64 released smoothly.
    [043] Furthermore, after the engagements between the convex parts 35 and the through holes 64 are released, in the first member 11 and the second member 12, a relative position relationship is controlled in the parts of the protruding part part 16 and parts of claw 55. Accordingly, as illustrated in figure 9, the second member 12 allows the centerline to incline much in the right to left direction with respect to the projection direction of the protruding part part 16. In addition, the part of protruding piece 16 has a flexible property, and can bend in the right to left direction, so that the second member 12 can be displaced in a relatively free direction with respect to the base part 15 of the first member 11. Consequently, even if the direction of the load acting on the second member 12 is oblique with respect to the direction of projection of the protruding part part 16 in the initial state, the second member 12 can be smoothly displaced with respect to the first member 11.
    [044] As illustrated in Figure 8, a displacement with respect to the first member 11 of the second member 12 can be performed until the inverted stop surface 56 of each grip part 55 rests against the inverted stop surface 41 of the expanded front part 17 A state in which the inverted stop surface 56 of each claw part 55 abuts against the inverted stop surface 41 of the expanded front part 17 is a state after displacement, it is only necessary to tilt the retaining piece 54 by gripping a end of each retaining piece 54 such that each retaining piece 54 is mutually separated.
    [045] In the following, a structure in which a trim 101 is attached to an upper part of the front pillar 100 of the automobile using the fastener 10 will be explained. Figure 10 is a horizontal cross-sectional view illustrating a structure around the top of front pillar 100 on a left front side of the automobile. The coordinates of figures 10 and 11 define an automobile's direction of travel as forward.
    [046] As illustrated in figure 10, the upper part of front pillar 100 is structured by an upper inner front pillar 111 provided on an inner side of the vehicle; a front pillar upper portion gusset 112 provided on an outer side of the vehicle from the front inner upper pillar 111 and forming a closure structure with the front inner upper pillar 111; and an outer panel 113 provided on the outer side of the vehicle of the upper front pillar reinforcement 112, and forming the closure structure with the upper front pillar reinforcement 112. In the front inner upper pillar 111, a through hole is formed 114 into which the base portion 15 of the fastener 10 fits. The through hole 114 is formed in a square shape, and is formed to a size that the base portion 15 can fit to a predetermined tolerance.
    [047] On one side of the front surface of the upper part of the front pillar 100, a left end of a front glass 115 is disposed, and a space between both members is covered by a molding 116. At the rear of the upper part of the pillar front 100, a side door 120 is provided comprising a side glass 121. In a space between the top of the front pillar 100 and the side door 120, time strips 122 and 123 are arranged.
    [048] On the inner side of the vehicle of the upper inner front pillar 111 a finish 101 is arranged as an inner member having a shape that swells towards the inner side of the vehicle. The finish 101 comprises a seat portion 125 on a reverse face (one face facing the outside of the vehicle) for securing the fastener 10. The seat portion 125 is structured by a pair of wall pieces 126 and 126 provided. to project to the reverse face of finish 101; a top panel portion 127 forming a bridge such as to connect both ends of a pair of wall portions 126 and 126; and a cut 128 formed on the top panel portion 127. As illustrated in Figure 1, at section 128, one end connects to an end portion of the top panel portion 127. A width of the cut 128 is formed on the size at which the portion cylinder 51 can fit to a predetermined tolerance, and is also formed less than a distance between the projecting ends of both collar parts 59. A length of cut 128 is formed into a length that approximately corresponds to a length in the direction of the collar. front to back of the cylindrical portion 51. A thickness of the top panel portion 127 is formed in a size in which the top panel portion 127 can be fitted between the collar portion 59 of the second member 12 and the flange portion 61.
    [049] In a space 129 formed between the top inner front pillar 111 and the trim 101, an air bag 130 of a side curtain air bag device in a folded state is housed. The side curtain air bag device comprises an inflation member which is not shown in the figures, and when a collision of a vehicle is detected, the side curtain air bag device detonates the inflation member so as to inflate and expand the air bag 130.
    [050] A method in which the trim 101 is secured to the front inner top pillar 111 using the fastener 10 will be explained. First, as illustrated in Figure 1, the fastener 10 is slid in a direction of an arrow 201, and the cylindrical portion 51 is inserted into the cut 128. The fastener 10 secures the top panel portion 127 between the collar portion 59 and the flange part 61. At that time, the elastic pressing part 63 presses the top panel part 127 to one side of the collar part 59 and improves a firm fastening property between the second member 12 and the top panel part 127.
    [051] Next, the base portion 15 is moved in a direction of an arrow 202, and is inserted into the through hole 114 of the upper inner front pillar 111. At this time, the cantilevered pieces 24 slant into the base portion 15, and the claw parts 25 pass through the through hole 114. An insertion of the base part 15 into the through hole 114 is carried out until the impulsive stop surfaces 32 of the claw parts 31 abut against a circumferential edge part of the through hole 114. In this state, the cantilever parts 24 return to an initial position, the inverted stop surfaces 26 of the claw portions 25 facing an inverted face side of the upper inner front pillar 111, and the upper inner front pillar 111 being secured between the claw parts 31 and the claw parts 25. In addition, each elastic piece 66 abuts against the upper front inner pillar 111 so as to prevent the second member 12 from swinging. In the way mentioned above, as illustrated in Figure 11, the finish 101 and the upper inner front pillar 111 are connected via the fastener 10. Eventually, after the base part 15 is inserted into the through hole 114, the cylindrical part 51 can be inserted in cut 128. An engagement between the first member 11 and the upper inner front pillar 111, and an engagement between the second member 12 and the finish 101 are made more solidly than the engagement between the convex parts 35 and the holes bystanders 64.
    [052] As mentioned above, the upper front inner pillar 111 and the trim 101, which are mutually connected through the fastener 10, receive expansion pressure from the air bag 130 in a separating direction from each other when the vehicle collision is detected, and the air bag 130 inflates. The expansion pressure of the air bag 130 is transmitted to the first member 11 connected to the upper front inner pillar 111, and the second member 12 connected to the trim 101, so that the engagement between the convex parts 35 and the through holes 64 is released . Then, as illustrated in Figure 11, the second member 12 is moved along the protruding piece part 16 until the second member 12 collides with the expanded front part 17. In this way, the front inner top pillar 111 and the finish 101 are mutually separated only by a length of relative displacement with the first member 11 of the second member 12, so that a space is formed between the upper front inner pillar 111 and the trim 101. Through the space, the air bag 130 expands into the interior of the vehicle.
    [053] As illustrated in figures 10 and 11, since the air bag 130 is disposed in a part of the space 129, the air bag 130 inflates so that a load acts on the second member 12 in an oblique direction with respect to the AA direction. projection of the protruding part part 16. As mentioned above, in the fastener 10 of the present embodiment, in a state in which the convex parts 35 and the through holes 64 are engaged, the first member 11 and the second member 12 are displaceable ( rotate) as the center of the convex parts 35 and in a state in which the engagement between the convex parts 35 and the through holes 64 is released, the second member 12 is supported on the protruding part part 16 so as to be able to tilt with respect to the Projection direction of the protruding part part 16. Since the protruding part part 16 can bend, even in a case in which the load acts on the second member 12 in the oblique direction with respect to the projection direction of the protruding part part 16, the second member 12 can be smoothly displaced with respect to the first member 12. That is, twisting between the second member 12 and the first member 11 is prevented, so that when a desired load acts on the fastener 10, the fastener 10 can change a relative position between the second member 12 and first member 11. In this way, in a normal time, the fastener 10 can fix in a stable manner. the finish 101 to the front inner top pillar 111. In addition, when the air bag 130 inflates, the fastener 10 may deform (a change in position of the second member 12 relative to the first member 11) by the desired load so as not to prevent it from the 130 air bag inflates. Furthermore, in a state in which an engagement between the first member and the second member is released, the second member may further incline with respect to the base portion of the first member so as to be able to change an angle of the finish 101 with respect to the Front inner top pillar 111, and being able to open an opening for expansion of the air bag 130 into the vehicle additionally wide.
    [054] Although the explanation of a specific modality ends here, the present invention is not limited to the modality mentioned above, and can be broadly transformed. For example, convex parts 35 can be provided in the circumferential wall part 62 of the second member 12, and through holes (concave parts) 64 engaging with the convex parts 35 can be provided in the base part 15. In addition, the part of protruding piece 16 is not limited to a plate shape or a belt shape, and can be formed into a bendable wire shape. Furthermore, the engagement between the first member 11 and the upper inner front pillar 111, and the engagement between the second member 12 and the finish 101 in the embodiment are an example, and the present invention may have, until now, known various coupling structures. 10 fastener 11 first member 12 second member 15 base part 16 protruding part part 17 expanded front part 35 convex parts (engaging parts) 51 cylindrical part 52 through hole 53 cutouts 54 retaining parts (elastic parts) 55 claw-like parts ( projections) 59 collar parts 61 flange part 62 circumferential wall part 64 through holes 71, 72 voids (gaps) 100 front pillar top 101 finish 111 front inner top pillar 112 front pillar top part reinforcement 113 outer panel 114 through hole 125 seat part 126 wall part 127 top panel part 128 cut 130 air bag
