The shock absorber (10) is provided with an outer cylinder (17) and a bracket (18) having a pair of extension parts (27, 28). The outer cylinder (17) has an opening, and a fixed inner cylinder is inserted into the outer cylinder (17). The pair of extension sections (27, 28) extend outward in the radial direction of the outer cylinder (17) from different positions spaced apart in the circumferential direction of the outer cylinder (17). Holes (35-38) and rigidity reducing sections (41, 42) are provided in the pair of extension sections (27, 28). The hole portions (35-38) are provided at positions facing attachment holes of the attachment member disposed between the pair of extension portions (27, 28). The rigidity-reducing sections (41, 42) are disposed at the same position as the holes (35-38) in the axial direction of the outer cylinder (17) and at positions on the outer cylinder (17) side with respect to the holes (35-38). The rigidity of the rigidity reducing parts (41, 42) is lower than a position different from the arrangement position.
该缓冲器(10)具备外筒(17)和具有一对延伸部(27、28)的支架(18)。外筒(17)具有开口,在内部插入固定内筒。一对延伸部(27、28)从在外筒(17)的周向上分开的不同的位置分别向外筒(17)的径向上的外侧延伸。在一对延伸部(27、28)上设置有孔部(35~38)和刚性降低部(41、42)。孔部(35~38)设置在与配置于一对延伸部(27、28)间的安装部件的安装孔对置的位置。刚性降低部(41、42)配置在与孔部(35~38)在外筒(17)的轴向上的相同位置、且比孔部(35~38)靠外筒(17)侧的配设位置。刚性降低部(41、42)的刚性比与该配设位置不同的位置低。
