Claims

[Claims for Utility Model Registration] Fixed to a rotating shaft at a predetermined distance from each other,
first and second rotating bodies that are rotationally driven; a disk mounting portion formed on either one of the first and second rotating bodies; and the rotation between the first and second rotating bodies. a ball holding means disposed on a shaft so as to be slidable in its axial direction, and having a ball holding section each accommodating a plurality of balls in at least three or more radial directions; urging means for urging the balls to elastically abut against a flat surface formed perpendicular to the axial direction, and an outer ball among the plurality of balls in the ball holding section is arranged to press against the disk. When a disk is placed on the placement portion and a pressing force directed toward the center is applied by the inner circumferential surface of the center opening of the disk, the relative position with respect to the adjacent ball changes in the axial direction, Centering of a disk, characterized in that the center of the ball is previously offset in the axial direction with respect to the center of the adjacent ball so that the ball holding means moves against the urging force of the urging means.
