Abstract:
A base part (92) of a friction member (22) is configured from a perforated disk-shaped bottom part (101) and a tube part (102) that extends from the outer peripheral side of the bottom part (101) in the axial direction. An elastic rubber part (91) is provided with a minimum inner diameter part (137) formed on the inner peripheral side, and enlarged-diameter parts (138, 139) at both axial sides of the minimum inner diameter (137). A tube part fixing surface (126) fixed to the tube part (102) is provided on the outer peripheral side. A notch part (151) is formed at least partially on the tube part (102) side of a release surface (135) facing in the direction axially opposite to a bottom part fixing surface (128) fixed to the bottom part (101). The deepest part (155) of the notch part (151) is shallower than the axial direction position of the minimum inner diameter part (137).
