を特徴とするデイスクの回転駆動装置。 A center hole and a drive pin insertion hole provided at the center of the disk and a position eccentric from the center are respectively inserted into a center pin and a drive pin provided at the center of the turntable and a position eccentric from the center. The disc is configured to be rotated by the drive pin as the turntable rotates, and at this time, the drive pin urges the disc to move in a direction away from the center of the turntable. In the disk rotation drive device, the drive pin inserted into the drive pin insertion hole is pressed against the side surface of the center pin to position the center of the disk at the center of the turntable. 1. A disk rotary drive device, characterized in that the drive pin insertion hole is provided with a locking portion that locks in a chucking position pressed against the front side in the rotational direction and the outer peripheral side of the drive pin insertion hole.
