ABSTRACT:
A chucking mechanism is operable to detachably set thereon a discoid disk. The chucking mechanism includes a center case, a claw member, an elastic member, and a turn table. The claw member includes, a claw portion, and a movement support portion The center case includes a movement pivot receiving portion. A support point extending continuously from the movement pivot portion is arranged radially inwardly of the movement pivot portion at the movement support portion, and axially upward movement of the tip portion is substantially prevented since the support point makes contact with the movement pivot receiving portion, and a top surface of the movement support portion makes contact with a bottom surface of the top plate portion.
