Claims

[Claims for Utility Model Registration] (1) A disk positioning member, a clamp member disposed opposite to the positioning member and having a movable part, and a movable part of the south positioning member and the clamp member. In the disk clamping device, the disk is arranged between the positioning member and the crank member, and the inner periphery of the disk is clamped by the attraction force of the magnetic attraction portion. The clamp member is
It has a holding member that comes into contact with the disk and movably houses the movable part, and a moving member that can move integrally with the moving part, and an elastic body is interposed between the holding member and the moving member. A disk clamp device characterized by: (2) The movable member has a handle made of a cylindrical body capable of storing an elastic body, and a screw member connecting the handle and the movable part, and the movable member and the movable member are connected in accordance with rotation of the screw member. The disk clamp device according to claim (1) of the utility model registration, characterized in that the distance to the movable part is made variable.
