In addition, to ensure the rigidity of the frame, it is necessary to further increase the stiffness such as by thickening the engine hook supports. As a result, there has been a problem that the weight around the engine increases.
    [006] In addition, on the motorcycle described above in patent document 1, the weight of the engine is supported by means of collars and fastening elements (screws). As a result, it is necessary to adequately ensure the strength of the collars and fasteners, in order to be able to withstand the load related to the rigidity of the frame and the load, related to the weight of the motor through the collars and fasteners . Therefore, there has also been a problem, in this regard, in which the weight of the engine's suspension structure increases.

    5/29 ten side) of the chassis frame in the direction of the vehicle width. In addition, the lower suspension portion suspends the motor by fixing it directly from the plate portions and lower hook portions. As a result, it is possible to directly support the weight of the engine, through which the engine's support stiffness can be increased. Therefore, it is possible to achieve weight reduction on a motorcycle, which includes an engine hook bracket, improving the chassis frame stiffness and the engine support stiffness through distribution with the upper suspension portion and the suspension portion bottom. In addition, since the components of the lower suspension portion are few compared to the upper suspension portion, it is possible to configure the width of the vehicle to be compacted. As a result, it is possible to reduce the weight of a lower portion of the engine, through which the centralization of mass can be achieved.
    [0016] According to the second aspect of the invention, the protrusion portions, plate portions, collar portions and upper hook portion can be fixed between the pair of descending tubes from the outside of the descending tubes by means of the upper portion fixing. As a result, the engine that serves as a rigid element can be configured to be interposed by down pipes, which are a part of the chassis. Therefore, engine stiffness can be used effectively to improve chassis stiffness.
    [0017] According to the third aspect of the invention, the upper suspension portion and the lower suspension portion are arranged linearly along the direction in which the downward tube extends in a side view. As a result, it is possible to group the load direction after supporting the engine by the upper suspension portion and the lower suspension portion in the direction in which the downline extends. Therefore, it is possible to improve the balance of riPetition 870180051950, of 06/18/2018, pg. 8/40
    6/29 chassis frame, where the engine load can be supported with a lightweight structure.
    [0018] According to the fourth aspect of the invention, the rotational load applied to the plate portion on the upper suspension portion can be received by the fixing portion. As a result, the support stiffness of the engine can be further increased.
    [0019] According to the fifth aspect of the invention, the fixing stay of the cover element for fixing the cover element covering a lateral side of the chassis is provided between the fixing portion of the plate portion and the upper suspension portion . As a result, it is possible to increase the mounting force of the cover element.
    [0020] According to the sixth aspect of the invention, it is possible to adequately define the load of the engine support in the upper suspension portion, in the lower suspension portion and in the rear suspension portion, by the arrangement of the upper suspension portion, the portion lower suspension and the rear suspension portion, with reference to the crankshaft, which is weighed between the engine components. As a result, optimization of the engine's suspension positions can be achieved, whereby it is possible to achieve a weight reduction in each of the suspension portions and in the chassis frame. In addition, the engine can be made to contribute to an improvement in the rigidity of the chassis frame.
    [0021] According to the seventh aspect of the invention, the main load acting on the lower suspension portion is the traction force from the weight of the engine. As a result, the plate portion can sufficiently exhibit a function to increase the stiffness of the engine support, even if a part of it between the upper suspension portion and the lower suspension portion is bent. Therefore, it is possible to achieve a size reduction by doubling

    [0080] A through hole 110 is provided in the third part of the plate 101c. A lower hook screw 126 is inserted into the through hole 110.
    [0081] The hook support of motor 100 disposed on the left side of motorcycle 1 in the direction of the vehicle width was explained below. Since the configuration of the engine hook support 100 disposed on the right side of the motorcycle 1 in the direction of the vehicle width is substantially the same as the configuration of the aforementioned engine hook support 100 disposed on the
    Petition 870180051950, of 06/18/2018, p. 24/40
    22/29 left side towards the width of the vehicle, redundant explanations to the contrary will be omitted.
    [0082] Next, the upper suspension portion 112 and the lower suspension portion 124 will be explained while referring to figures 3 to 6.
    [0083] As shown in figures 3 to 6, the upper suspension portion 112 suspends the motor 20 by fixing the descending tubes 9, the plate portions 101, collar portions 106 and the upper hook portion 22 in a linearly arranged state towards the width of the vehicle.

    [0085] As shown in figure 5, the pair of descending tubes 9, the cross member 9a and the upper suspension portion 112, thus form a rigid rectangular body in a front view. As a result, it is possible to make the upper hook portion 22 of the motor 20 contribute to an improvement in the rigidity of the frame of the chassis 5. [0086] As shown in figures 3 to 6, the suspension portion
    Petition 870180051950, of 06/18/2018, p. 25/40
    Lower 23/29 124 suspends the motor 20, by fixing the plate portion 101 and the lower hook portion 23. More specifically, the lower suspension portion 124 includes plate portion 101, the lower hook portion 23 adjacent to the plate portions 101, the lower hook screw 126, and nut 126a threading to the lower hook screw 126. The lower hook screw 126 is arranged to penetrate in the direction of the width of the vehicle through plate portions 101 and the portion bottom hook 23, and is configured to be able to fix directly from outside the plate portions
    101. A main end of the lower hook bolt 126 is secured by nut 126a.
    [0087] The upper suspension portion 112 and the lower suspension portion 124 configured in the above form are arranged linearly along a direction in which the downward tube 9 extends in a side view, as shown in figure 4.
    [0088] Furthermore, the upper suspension portion 112 and the lower suspension portion 124 are, respectively, above and below crankshaft 26, in a side view, as shown in figure 4.
    [0089] The folded portion 111 of the plate portion 101 is formed into a portion of the plate portion 101 between the upper suspension portion 112 and the lower suspension portion 124, and folds so as to project forward in with respect to a line 135a connecting the upper suspension portion 112 and the lower suspension portion 124. [0090] Next, the rear suspension portion 130 will be explained with reference to figure 4. As shown in figure 4, the suspension portion rear 130 is configured to include a pair of upper hook stays of engine 132, and a fixing screw 133 and nut 133a (see figure 6) that rolls into this fixing screw 133. An upper portion of the rear portion of the engine 20 is stuck
    Petition 870180051950, of 06/18/2018, p. 26/40
    24/29 by means of the fixing screw 133 and the nut 133a for the upper hook stay of the engine 132. The rear suspension portion 130 thus suspends the upper part of the rear portion of the engine 20. [0091] The axle crank 26 is arranged within a triangularly shaped region 135 connecting the upper suspension portion 112, the lower suspension portion 124 and a rear suspension portion 130, in a side view, as shown in figure 4. Region 135 of triangular shape is configured from the three lines 135a, 135b and 135c. Line 135a is a line connecting the upper suspension portion 112 and the lower suspension portion 124. Line 135b is a line connecting the upper suspension portion 112 and the rear suspension portion 130. Line 135c is a line connecting the lower suspension portion 124 and the rear suspension portion 130.
    [0092] As previously described, sub-frames 9b, 9c, 9d and 9e (see figure 4) are provided between the down tubes 9 and the main frames 7, and form a truss structure. As shown in figure 4, line 135b configuring region 135 is substantially parallel to sub-frame 9c. In addition, line 135C configuring region 135 is substantially parallel to sub-frame 9e. Therefore, according to this suspension structure of the engine 20, the engine 20 alone can reinforce the longitudinal rigidity of the chassis frame 5 similarly to sub-frames 9c and 9e.
    [0093] Furthermore, the fixing screw 118 and the nut 118a are provided above the upper suspension portion 112 as fixing portions for fixing the upper ends of the plate portions 101 and the second protrusion portion 142 of the descending tubes 9. The fixing screw 118 is inserted into the second protrusion portion 142 and the through hole 107 of the plate portion 101, and is scratched to the welded nut 104 of the plate portion 101. The upper end of the plate portion 101 is thus secured to the descending tube
    Petition 870180051950, of 06/18/2018, p. 27/40
    25/29
    9.
    [0094] The fixing stay of the covering element 146 is provided between the fixing screw 118 fixed to the plate portion 101 and the upper suspension portion 112. The fixing stay of the covering element 146 is a metallic element that holds the inner hood 92, which serves as a cover element that covers one side of the chassis. The fixing stay of the cover element 146 is made so that it is fixed to the plate portion 101 by the screw 148 and by the nut 149. The screw 148 is inserted into the through hole 109 of the plate portion 101. Then, the nut 149 is threaded to the front end of the screw 148.
    [0095] Each of the effects indicated below is exercised in accordance with motorcycle 1 of the present modality explained in the above.
    [0096] The motorcycle 1 of the present modality includes the frame of the chassis 5; the motor 20 with the hook portion 21, the downstream pair 9; the hook support of the motor 100 with the plate portions 101 and collar portions 106, and joining the down pair of pipes 9 with the hook portion 21, the upper suspension portion 112, and the lower suspension portion 124 The upper suspension portion 112 suspends the engine 20 by fixing the downward pipe 9, the plate portion 101, collar portions 106 and the upper hook portion 22 in a state arranged linearly in the direction of the vehicle width. The lower suspension portion 124C suspends the motor 20 by fixing the plate portions 101 and the lower hook portion 23.
    [0097] The upper suspension portion 112 suspends the engine 20 by fixing the downward pipe 9, the plate portions 101, collar portions 106 and the upper hook portion 22 in a state arranged linearly in the direction of the vehicle width . As a
    Petition 870180051950, of 06/18/2018, p. 28/40
    As a result, it is possible to increase the rigidity (lateral stiffness) of the chassis 5 in the direction of the vehicle width.
    [0098] In addition, the lower suspension portion 124 suspends the motor 20 by means of fixing directly from the plate portions 101 and the lower hook portion 23. As a result, it is possible to directly support the weight of the motor 20, through the which the supporting stiffness of the motor 20 can be high. Therefore, it is possible to achieve a weight reduction by improving the rigidity of the chassis 5 and the rigidity of the engine support 20 by means of the distribution with the upper suspension portion 112 and the lower suspension portion 124.
    [0099] Furthermore, since the lower suspension portion 124 has few components compared to the upper suspension portion 112, it is possible to configure the width of the vehicle to be compacted. As a result, it is possible to reduce the weight of a lower portion of the motor 20, through which the centralization of the mass can be achieved.
    In addition, on motorcycle 1 of the present embodiment, the upper suspension portion 112 includes the first protrusion portion 141 and second protrusion portion 142, the plate portions 101, the collar portions 106, the upper hook portion 22, the pair of descending tubes 9, and 114 upper screw hanger. The upper hook screw 114 is arranged to penetrate through protrusion portions 141, 142, plate portions 101, collar portions 106 and upper hook portion 22 in the direction of the vehicle width, and is configured to be able to clamp out of the pair of descending tubes 9.
    [00101] As a result, hump portions 141, 142, plate portions 101, collar portions 106 and upper hook portion 22 arranged in the direction of the vehicle width between the downward pair of tubes 9 can be fixed from outside the tubes
    Petition 870180051950, of 06/18/2018, p. 29/40
    27/29 descendants 9 by the upper fixing element. The motor 20 that serves as a rigid element can thus be configured to interpose down pipes 9. Therefore, the rigidity of the motor 20 can be effectively used to improve the rigidity of the frame of the chassis 5.
    [00102] In addition, the motorcycle 1 of this modality also includes the front tube 6, which forms part of the frame of the chassis 5 and supports the front forks 3 to be able to rotate. Down tubes 9 extend linearly from front tube 6 downwards. The upper suspension portion 112 and the lower suspension portion 124 are arranged linearly along the direction in which the downward tube 9 extends in a side view.
    [00103] As a result, it is possible to group the load direction by supporting the engine 20 by the upper suspension portion 112 and by the lower suspension portion 124 in the direction in which the downline 9 extends. Therefore, it is possible to improve the stiffness balance of the frame of the chassis 5, in which the load of the motor 20 can be supported with a lightweight structure.
    [00104] Furthermore, on motorcycle 1 of the present embodiment, the fixing screws 118 for securing the plate portions 101 and the descending tubes 9 are provided above the upper suspension portion 112. As a result, the rotating load acting on the plate portion 101 around the upper suspension portion 112 can be received by the fastening screws 118. Therefore, the supporting stiffness of the motor 20 can be further increased. [00105] Furthermore, on the motorcycle 1 of the present embodiment, the fixing stay of the cover element 146 to secure the inner hood 92 is provided between the fixing screws 118 of the plate portions 101 and the upper suspension portion 112. As a result, it is possible to increase the mounting force of the inner canopy 92.
    Petition 870180051950, of 06/18/2018, p. 30/40
    28/29 [00106] Furthermore, motorcycle 1 of the present embodiment further includes the rear suspension portion 130. The upper suspension portion 112 and the lower suspension portion 124 are respectively arranged above and below the crankshaft 26 , in a side view. The crankshaft 26 is arranged within region 135 in a triangular shape formed by connecting the upper suspension portion 112, the lower suspension portion 124 and the rear suspension portion 130, in a side view.
    [00107] As a result, it is possible to properly define the support load of the engine 20 in the upper suspension portion 112, in the lower suspension portion 124 and in the rear suspension portion 130, by the arrangement of the upper suspension portion 112, the lower suspension frame 124 and the rear suspension portion 130 with reference to the crankshaft 26, which is weighed between the components of the engine 20. Therefore, optimization of the suspension positions of the engine 20 can be achieved. A weight reduction can be obtained for the upper suspension portion 112, the lower suspension portion 124, the rear suspension portion 130 and the chassis frame
    5. In addition, the motor 20 can be made to contribute to an improvement in the rigidity of the chassis frame 5.
    [00108] In addition, on motorcycle 1 of the present embodiment, a portion of the plate portion 101 between the upper suspension portion 112 and the lower suspension portion 124 folds in order to project forward in relation to the line 135a which joins the upper suspension portion 112 and the lower suspension portion 124, in a side view.
    [00109] The main load acting on the lower suspension portion 124 is the tractive force from the weight of the engine 20. As a result, the folded portion 111 of the plate portion 101 can sufficiently exhibit a function to increase the stiffness of Support
    Petition 870180051950, of 06/18/2018, p. 31/40
    29/29 of the motor 20. Therefore, it is possible to achieve a reduction in size by providing the folded portion 111 of the plate portion 101 to contain the amount of projection to match the shape of the motor 20.
    [00110] Although one embodiment of the present invention has been explained in the foregoing, the present invention is not to be limited to the aforementioned embodiment, and changes are possible, as appropriate.
    [00111] For example, although the plate portion 101 of the hook support of the motor 100 has been explained to be formed in a substantially wide-V shape, in a side view, and having the folded portion 111 that folds out to project onto ahead, it is not limited to it. The hook support of the motor 100 can be configured so that the plate portion 101 is a linear shape, as a whole.
