Abstract
A tip portion of a claw member is, when the same is at a lowest position, axially above a bottom surface of an upper disk base of a multi-layered disk. By virtue of such configuration, the tip portion will not be caught between the upper disk base and a lower disk base of the multi-layered disk.
