A disk clamp device characterized in that the hub segment is elastically deformed around the elastic deformation portion, and the pressure contact portion is brought into pressure contact with the inner circumferential wall of the circular recess due to the elastic deformation. (2) The disk clamp device according to claim (1) of the utility model registration, characterized in that the elastic deformation portion is a notch formed in a side wall of a hub segment. (3) A disk clamping device according to claim (1) of the utility model registration, characterized in that the transition part between the flange part and the pressure contact part of the hub segment is a thin wall part, and the thin wall part is an elastically deformable part. .
