Document Type and Number:
WIPO Patent Application WO/2022/050065
Kind Code:
A1
Abstract:
A shock absorber (10) comprises an outer tuber (17) and a bracket (18) having a pair of extension parts (27, 28). The outer tube (17) has an opening in which an inner tube is inserted and fixed. The pair of extension parts (27, 28) are each formed so as to extend toward the radially outer side of the outer tube (17) from different positions that are spaced away in the circumferential direction of the outer tube (17). The pair of extension parts (27, 28) are provided with holes (35-38) and rigidity reduction parts (41, 42). The holes (35-38) are provided at positions corresponding to attachment holes in an attachment member that is to be disposed between the pair of extension parts (27, 28). The rigidity reduction parts (41, 42) are disposed at placement positions that are the same levels as the holes (35-38) in the axial direction of the outer tube (17), and that are closer to the outer tube (17) than the holes (35-38). The rigidity reduction parts (41, 42) have rigidity that is lower than that at positions other than said placement positions.
