Alternatively, the sliding portion 14 is connected to the lowerthe laying plate 15 by welding or by means of conventional fastening means.
    The sliding portion 14 is made with an upper surface 17 for supporting the gearthe tongue, so that the gear tongue can slide against the upper surface 17 of the sliding portion in connectionwith shift. The upper surface 17 of the sliding portion 14 extends in a plane substantiallyparallel to the washer portion 15. The upper surface 17 is offset verticallydirection relative to the pad portion 15, the upper surface 17 beingarranged higher than the washer portion 15. For example, the slide plate 12, orat least the sliding portion 14, made of a metal which results in low friction againstthe gear tongue. For example, the sliding plate 12, or at least the sliding portion 14,made of steel, molybdenum, nickel, chromium or other suitable metal or mixedthereof.
    The washer portion 15 is designed to receive a rail foot 18 of the support.the rail 11, so that the support rail 11 rests on the underlay portion 15. The rail foot 18 is oneconventional rail foot 18 projecting substantially horizontally for abutmentagainst a surface. The pad portion 15 includes a strip 19 for abutment againsta side surface of the rail foot 18 in a conventional manner and connecting element 20to enable the outside of the support rail 11 to be connected in a conventional manner.
    The sliding portion 14 is formed with a projection 21 to form a tighteningat least substantially parallel to the support rail 22 running space 22 forreceiving a portion of the rail foot 18 so that the rail foot 18 projects into the space22 below the projection 21. The projection 21 is arranged at a distance from thethe loading portion 15 and, for example, at the upper portion of the sliding portion 14 adjacent tothe upper surface 17 of the sliding portion 14, the projection 21 projecting over the rail foot 18and overlaps the same. For example, the projection 21 projects substantiallyhorizontally. For example, the projection 21 projects in a direction substantially transversethe stretch of the support rail 11 and in the direction of the strip 19 and the strip 15 andconnecting element 20 or in the direction of a conventional waist 23 of10152025307support rails 11. For example, the projection 21 projects 10-80 mm, 20-60 mm, 30-50 mm and for example about 40 mm in the direction of the support rail 11, wherein aunderside of the projection 21, for example, is arranged at a distance of 2030 mm and, for example, about 22-25 mm from the washer portion 15.the position between the underside of the projection 21 and the washer portion 15 correspondsa height of the space 22.
    The space 22 is designed to receive a portion of the rail foot 18 and forreceiving the spring 13 to provide the resilient connection ofthe inside of the support rail 11. The spring 13 is designed to be inserted into the space 22 andbrought into abutment against the rail foot 18 for resilient attachment of the support rail 11.
    Thus, the space 22 is provided for receiving the spring 13 between the projections21 and the rail foot 18, the spring 13 being designed to abut in the space 22against the projection 21 and the rail foot 18 for clamping the support rails 11.The mat 22 is, for example, open in the stretch of the support rail 11, i.e. at both ends.
    The spring 13 is elongate and is arranged along the space 22 at leastsubstantially parallel to the support rail 11, as shown in particular in Fig. 4 andFig. 6.
    The projection 21 is made with a projection in the direction of the washer portion 15sliding flange 24, as shown in Fig. 2, to prevent accidental displacementof the spring 13 laterally in the direction of a free end of the projection 21 ordirection towards the waist 23 of the support rail 11. The flange 24 is designed for abutment againstan outer first long side or a portion of the outer first long side of the spring13, to prevent the spring 13 from inadvertently leaving the space 22 in one directionacross the length of the support rail 11 in a direction towards the waist 23 of the support rail 11.the portion 14 prevents the spring 13 from being displaced laterally in the opposite direction bythat an inner second long side of the spring 13 comes into contact therewith. Out-the projection 21 of the sliding portion 14 and the flange 24 of the projection 21 form a groove forthe spring 13, the spring 13 in the space 22 being partially enclosed bythe spring 21. When the spring 13 is arranged in the space 22, the first longitudinalof the spring 13 directed towards an inner side of the outlet formed by the flange 23the spring 21, an upper side of the spring 13 being directed towards a lower sideof the projection 21, and wherein the other long side of the spring 13 is directedagainst a side portion of the sliding portion 14 at the same time as a underside of the spring 1310152025308abuts against the washer portion 15 in the space 22. Thus, the spring 13 isat least substantially radially enclosed by the slide plate 12.
    Referring to Figs. 7 and 8, the spring 13 is shown in more detail accordinglywith an embodiment of the present invention. The spring 13 is in the embodiment shownperformed in the form of a leaf spring. The spring 13 comprises a central portion 25, aangular portion 26 and a stop in the form of a flange portion 27. The central portion 25 is formedwith a curvature. For example, the middle portion 25 is designed so that a convex sideof the spring 13 is made for abutment against the washer portion 15 and a con-the hollow side of the middle portion is made for abutment against the underside of the projection 21inside the flange 24. The angular portion 26 projects at an angle from the central portion, such asa substantially right angle. For example, the angular portion 26 projects from a firstend of the central portion 25 and includes a first end of the spring 13. Angularthe portion 26 projects in a direction towards the upper surface 17 of the sliding portion 14 and away from itthe pad portion 15, as shown in particular in Figs. 5 and 6. Thus, thethe angular portion 26 is substantially vertical when the device 10 is mounted ona substantially horizontal surface. The angular portion 26 is designed to preventunintentional displacement of the spring 13 in a direction along the support rail 11 throughabutment against a first side surface 28 of the projections 21 of the sliding portion 14.pelvis, the angular portion 26 is also designed to facilitate insertion of the spring 13in the space 22, the angular portion 26 forming an abutment surface for a hammeror equivalent, so that the spring 13 can be inserted into the hammer by means of the hammerthe space 22 axially in a direction along the support rail 11.
    The flange portion 27 projects from the central portion 25 in the corresponding direction asangular portion 26, i.e. in the direction of the upper surface 17 of the sliding portion 14. The flange portion 27is designed to prevent accidental displacement of the spring 13 axially in a directional direction.along the support rail 11 by abutment against a first side surface 28opposite second side surface of the projection 21 of the sliding portion 14, i.e. on other sitesWhen mounting the spring 13, the flange portion 27 is inserted axiallyin the space 22 in a direction along the support rail 11. Thus, the spring 13 is inserted into afirst end of the space at, for example, the first side surface 28 of the sliding portion 14.
    Thereafter, a force is applied to the angular portion 26 of the spring 13 in a longitudinal directionthe support rail 11, the spring 13 being forced into the space 22 in the axial direction parallelwith the support rail 11 while forming the spring action in the radial direction between10152025309the projection 21 and the rail foot 18. For example, the force is applied to the spring 13using a conventional tool, such as a hammer, sledgehammer or similarnande. The spring 13 is inserted into the space 22 until the flange portion 27 comes out througha second end of the space 22 at the second side surface of the sliding portion 14, whereinthe flange portion 27 through the inherent suspension 13 of the spring 13 is pressed up andcomes into abutment against the second side surface of the blast 21. For example,13 into the space 22 until the angular portion 26 comes into abutment against thethe first side surface 28 of the spring 21 Thus, the spring 13 extends axially along the wholethe space 22 and along the rail foot 18 parallel to the support rail, as shownin particular of Fig. 4 and Fig. 6. For example, the spring 13 partially encloses the projection21. For example, the spring 13 abuts against the underside of the projection 21, first sidedoyta and other side surface.
    Referring to Fig. 9 and Fig. 10, an alternative embodiment ofthe spring 13 in accordance with the present invention. In accordance with that in Fig. 9and Fig. 10, the spring 13 is provided with a stop 29 forlying against the second side surface of the projection 21 to prevent accidental displacementof the spring 13 axially in a rearward direction along the support rail 11. The stop 29 ismade protruding from an upper side of the spring 13, the stop 29 projectingout in the same direction as the angular portion 26. For example, the stop 29 projectssubstantially perpendicularly upwards from the upper side of the middle portion 25 when the middle of the spring 13portion 25 is arranged in the space 22. The stop 29 is for instance made in the form ofa resilient pipe section or a spring pin or the like. For example, isthe stop 29 is formed by a tube portion provided with a slot, so that the stop 29 is resilient.radial direction. The stop 29 is arranged in a recess 30 in the spring 13.
    For example, the recess 30 is continuous and arranged at the spring 13other end. The recess 30 is made for receiving a first part ofthe stop 29, a second part of the stop 29 projecting from the recess 30and a top of the spring 13. The stop 29 is, for example, detachable, whereinthe stop can be removed from the spring during disassembly.
