no. 1 Embodiment
[0055] 1 is a cross-sectional view showing a state in which a bracket 10 according to a first embodiment of the present invention is mounted on a vehicle, figure 2 is its exploded view.
[0056] In the figure, 12 is a piston rod of a shock absorber, 14 is a vehicle body, 16 is a spring seat supporting the upper end of the coil spring, and 18 is a bearing fixed to the upper end 12a of the piston rod by a nut 20 .
[0057] In the plate-shaped vehicle body 14, there is provided a recess 22 that is recessed upward and opened downward in a convex shape. The side wall portion 24 of the recess 22 is formed in a conical cylindrical shape whose diameter becomes smaller as it goes upward, and a circular opening 28 is provided in the upper wall portion 26 . The upper wall portion 26 extends radially inward from the upper end of the side wall portion 24, and is formed in the shape of a ring plate by providing an opening 28 inside, and the upper end portion 12a of the piston rod is insert...
no. 2 Embodiment
[0075] According to Figure 6~ Figure 10 The bracket 10A of the second embodiment will be described. The structure of the stopper rubber part 42 of the second embodiment is different from that of the above-mentioned first embodiment. The structure other than the stopper rubber part is the same as that of the first embodiment, and the same symbols are assigned to the same parts, and the description thereof will be omitted.
[0076] Figure 6~ Figure 8 As shown, in this embodiment, on the lower surface 42b of the stopper rubber portion 42, the plurality of spherical crown protrusions 52 are arranged at equal intervals along the entire circumference of the lower surface 42b in a double inner and outer ring shape. Further, the spherical crown protrusions 52 are arranged in an inner circular annular row 56 and an outer circular annular row 58 which are different from each other in the circumferential direction. That is, in the inner annular row 56 and the outer annular row 58, t...
