Abstract:
A movement pivot receiving portion which receives a movement pivot portion of a claw member and a movement support receiving portion which receives a movement assist portion of the claw member are arranged radially within a cylindrical portion of a center case. By virtue of such configuration, both receiving portions are designed with a greater degree of freedom within a space between an inner circumferential surface of the cylindrical portion and an outer circumferential surface of a base portion. Therefore, the claw member may be designed to have a preferable thickness while achieving a preferable movement of in an axial direction.
