ABSTRACT:
A claw member includes at a radially inward surface thereof a protrusion inclined surface in order to minimize deformation occurring in an axial direction to an elastic member which is a coil spring. The protrusion inclined surface is preferably inclined, when a tip portion of the claw member is at an axially lowest point, to be substantially perpendicular to the central axis, or such that the further radially inward a portion thereof is the axially lower the portion is. By virtue of such configuration, the protrusion inclined surface minimizes deformation occurring to the elastic member in the axial direction.
