Abstract

A lower spring seat 31 is mounted on a cylinder including a damper device to support a wheel-side end portion of a coil spring 30 disposed between a vehicle body and a wheel. The lower spring seat 31 includes: a mounting portion on which the wheel-side end portion of the coil spring 30 rests; and an enlarged diameter portion disposed on a side of the mounting portion opposite to the cylinder 10 and disposed between the coil spring 30 and the wheel. The mounting portion and the enlarged diameter portion are each made of a resin material.

First claim

1 . A spring seat mounted on a cylinder comprising a damper device to support a wheel-side end portion of a spring disposed between a vehicle body and a wheel, the spring seat comprising:
a mounting portion on which the wheel-side end portion of the spring rests; and an intermediate portion disposed on a side of the mounting portion opposite to the cylinder and disposed between the spring and the wheel, wherein the mounting portion and the intermediate portion are each made of a resin material, and the spring seat further comprises a metal reinforcing member at the mounting portion on a side of the wheel to receive a load of the spring, and does not comprise a metal reinforcing member at the intermediate portion on a side of the wheel.

2 . The spring seat according to claim 1 , wherein the intermediate portion comprises a strengthening member made of a material having a higher strength than materials of the mounting portion and the intermediate portion to keep the spring away from the wheel.

3 . The spring seat according to claim 1 , wherein the intermediate portion comprises
an outer portion disposed at an outside in a radial direction of the mounting portion, and a supporting portion connected to the outer portion and supported by the reinforcing member.

4 . The spring seat according to claim 3 , wherein the outer portion is inclined from a surface of the mounting portion on a side of the spring toward a side of the vehicle body.

5 . The spring seat according to claim 1 , further comprising a position deviation prevention mechanism configured to prevent a position deviation between at least two adjacent members among the mounting portion, the reinforcing member, and the cylinder.

6 . The spring seat according to claim 5 , wherein the position deviation prevention mechanism comprises
a protrusion portion disposed at one of the reinforcing member and the mounting portion and protruding in an axial direction of the cylinder, and a depression portion disposed at another one of the reinforcing member and the mounting portion and depressed in the axial direction to be fitted with the protrusion portion.

7 . The spring seat according to claim 5 , wherein the position deviation prevention mechanism prevents a position deviation between the mounting portion and the reinforcing member, and prevents a position deviation between the reinforcing member and the cylinder.

8 . The spring seat according to claim 5 , wherein the position deviation prevention mechanism comprises
a first rectangle disposed at one of the reinforcing member and a member comprising the mounting portion, and a second rectangle disposed at another one of the reinforcing member and the member and facing the first rectangle to be fitted with the first rectangle.
