In a friction member (22), a base section (92) is constituted by a bottom section (101) and a tube section (102). The bottom section (101) has a bored disk shape, and the tube section (102) has a cylindrical shape extending from an outer circumferential side of the bottom section (101) in the axial direction. An elastic rubber section (91) has a minimum inner diameter section (137), diameter expanding sections (138), (139) which are disposed at each side in the axial direction of the minimum inner diameter section (137). A tube section adhering surface (126) is installed at outer circumferential side of a tube section (102). A cutout section (151) is at least partially formed at a bottom section adhering surface (128) fixed to the bottom section (101) and the tube section (102) side of an open surface at an opposite side in the axial direction, and a deepest section (155) of the cutout section (151) is shallower than a position in the axial direction of the minimum inner diameter section (137). |
