A damper (D) includes a first portion (D1) facing a rib (43, 143) of a bushing (40, 140, 540), a second portion (D2) facing a rib (22, 122) of an inner hub (20, 120), and a connection portion (b) connecting the first and second portions (D1, D2) to each other. In a state in which a rotational force has not been applied between the bushing (40, 140, 540) and the inner hub (20, 120), the damper (D) includes a cross-sectional shape that defines a deformation-absorbing space (S1, S2) positioned between the first and second portions (D1, D2). The deformation-absorbing space (S1, S2) is deformed such that the first portion (D1) approaches the second portion (D2) in a state in which the rib (43, 143) and the rib (22, 122) have moved relatively by application of a rotational force between the bushing (40, 140, 540) and the inner hub (20, 120).
