Claims

[Scope of utility model registration request]

The support plate of the drive pin is loosely fitted into the spindle that rotates together with the turntable through an elongated hole, and a spring that moves and biases the support plate moves the drive pin between the front side in the direction of rotation of the turntable and the center of the turntable. The disk is energized to move in a direction away from the turntable, and the disk is engaged with the center pin of the turntable through its center hole, and the drive pin insertion hole provided eccentrically in the disk is engaged with the drive pin. In the disk rotation drive device configured to rotate the disk by a turntable, the support plate is configured to be swingable in the vertical direction about the support shaft, and the support plate is configured to be slidable on at least the upper surface of the elastic body. An elastic washer to which a slippery sheet is attached is fitted to the lower part of the support plate around the outer periphery of the support shaft, and with the slippery sheet in contact with the lower surface of the support plate, the elastic repulsive force of the elastic body is applied to the 1. A disk rotation drive device characterized in that the support plate is pressed upward to elastically support the support plate in a substantially horizontal state.
