Document Type and Number:
WIPO Patent Application WO/2020/195703
Kind Code:
A1
Abstract:
Provided is a suspension device including: an annular spring bearing (4) that supports one end of a suspension spring; an annular restricting member (5) that restricts movement of the spring bearing (4) toward the opposite side from the suspension spring; three cam parts (7A, 7B, 7C) that are provided so as to have a phase difference of 120 degrees in the circumferential direction of the restricting member (5); and three protrusion parts (6A, 6B, 6C) that are provided at regular intervals in the circumferential direction of the spring bearing (4). The cam parts (7A, 7B, 7C) each have a plurality of cam surfaces (7a, 7b) that have different heights in the axial direction. The cam surfaces (7a, 7b) respectively include inclined planes that have equal inclination angles. The protrusion parts (6A, 6B, 6C) have abutment surfaces (6a) that are inclined along the inclined planes and that can abut against the inclined planes.
