をすることは極めて困難である。 In the past, various proposals have been made for fiber-reinforced resin leaf springs in order to solve the problem of increased weight, which is a drawback of steel leaf springs, but conventional examples have sufficiently achieved ease of manufacture and cost reduction. It is not possible to do so, and it has not yet reached the stage of practical application. In particular, if glass fiber or carbon fiber is used for the leaf spring body, machining is almost impossible, and drilling, etc. is extremely difficult.

る。 The present invention will be explained below based on embodiments shown in the drawings. A leaf spring 1 made of fiber reinforced resin (hereinafter referred to as FRP) is laminated and fastened to an axle 4 via a pad 2 with a U bolt 3. One end 5a of the uppermost FRP leaf spring 5 is integrally molded to bulge out to form a recess 5b, and two bulges 5c and 5d with a substantially circular cross section are formed on both sides of the recess, so to speak. Form into a cocoon shape.
The concave portion 5b is supported by being sandwiched between two support pins 7 and 8 attached to a support member 6 such as a bracket, and one end 5a is rotatable between the support pins 7 and 8. be. Support member 6
is fixed to the frame 10 by rivets 9.

A concave portion 5f and two bulging portions 5g and 8h are formed in the same manner as in a, and are held between two support pins 12 and 13 attached to a support member 11. The support member 11 is pivotally attached to a bracket 15 by screws 14 so as to function as a shackle, and the bracket 15 is fixed to the frame 10 by rivets 16.

2 and 13 are fixed to the support members 6 and 11, respectively, but this can be done so that the two support pins can be rotated at equal intervals with respect to the support pins. The radius of curvature of the recesses 5b and 5f can be made smaller than that shown in the figure, and the gripping force of the leaf spring 5 in the longitudinal direction can be increased. Also FRP
If a separate metal plate is embedded in the surface of the concave portion 5b at the end of the leaf spring 5, it will have excellent wear resistance.
It can be a leaf spring made of FRP.

２図に仮想線で示す如く吸収する。 The present invention is configured as described above, and its operation will be explained below. One end 5a, 5e of the uppermost leaf spring 5 of the FRP leaf spring 1 does not require any bending or drilling, and can be easily formed into a cocoon shape by integral molding, and supports the supporting members 6, 11, respectively.
Support pins 7, 8 and 12, 13 attached to
The support members 6 and 11 prevent the support member from coming off in the lateral direction, and the bulges 5c, 5d, 5g, and 5h prevent the member from coming off in the longitudinal direction. Furthermore, since the ends 5a and 5e are rotatable in substantially the same manner as the eye of the conventional example, vibration of the leaf spring 1 is allowed. The rear support member 11 rotates around the screw 14 as a shackle and absorbs the expansion and contraction of the leaf spring 5 as shown by the imaginary line in FIG.
