れる。 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 top layer FRP leaf spring 5 is integrally molded to bulge and form a cylindrical shape, and a support member 6 that supports the cylindrical one end 5a is inserted in the axial direction and rotated. A one-sided open support portion 6a is formed to be movably supported. The width of the opening 6b is made considerably narrower than the diameter of the cylindrical end 5a of the leaf spring 5 to prevent the leaf spring 5 from slipping out from the opening 6b. is opened in a fan shape, and the leaf spring 5 is rotatable relative to the support member 6. Further, a lid 7 is attached to the front surface 6c with screws 8 to prevent one end 5a of the leaf spring 5 from coming out laterally through the opening 6b and preventing the opening 6b from expanding. The support member 6 constitutes a fixed spring bracket and is fixed to the frame 9 with screws 10.

る。 Next, since this support device can also be used to support the leaf spring 5 in the rear support member 11, that is, the shackle, the other end 5b of the leaf spring 5 has a cylindrical shape like the one end 5a. The opening 11b is opened in a fan shape, and the opening 11b is opened at one end 5b.
is rotatably supported, and a lid 12 is attached to the front face 11c of the support member 11 with screws 13,
The support member 11 is attached to the bracket 14 by screws 15.
The bracket 14 is rotatably attached to the frame 9 by a screw 15, and is configured to function in exactly the same manner as a conventional shackle.

One end 5a, 5b of the uppermost leaf spring 5 of the FRP leaf spring 1 does not require any bending or drilling, and is easily formed into a cylindrical shape by integral molding, and the support portion 6a of the support member 6, 11, respectively. , 11a, and is prevented from coming off in the lateral direction by the lids 7, 12, and the leaf spring 5
Since the openings 6b and 11b are narrower than the cylindrical diameter of the ends 5a and 5b in the longitudinal direction,
It does not slip out from the support parts 6a, 11a, and there is no problem even if a sudden force is applied during wind-up or the like. Furthermore, since the ends 5a and 5b are rotatable like the centerpiece of the conventional steel plate spring, vibrations of the plate spring 1 are sufficiently tolerated. The rear support member 11 rotates around the screw 15 as a shackle and absorbs the expansion and contraction of the leaf spring 5.
