記載のデイスク回転装置。[Claims for Utility Model Registration] 1. A turntable that is fixed to a rotating shaft and has a disk receiving part formed on its upper surface, and a turntable that is located closer to the shaft center than the receiving part and is movable in the axial direction. A center hub having a tapered surface formed on the upper surface for centering the disk, and an elastic member interposed between the turntable and the center hub to bias the center hub toward the tip of the rotating shaft. In the disk rotating device, the turntable has a sliding surface formed in the shape of a circumferential surface centered on the rotating shaft, and the center hub slides on this sliding surface to rotate in the axial direction. 1. A disk rotation device, characterized in that a turntable is provided with a stopper for preventing a center hub from coming off, the center hub being movably attached to the turntable and urged by the elastic member. 2. Claim 1, wherein a step is provided inside the shaft hole of the turntable, and the tip of the rotating shaft inserted into the shaft hole is in contact with this step.
Disk rotation device as described.
