せたことを特徴とするデイスク回転機構。 A turntable that is fitted and fixed to the outer circumference of the motor shaft, a stopper that is also fitted and fixed to the outer circumference of the motor shaft above the turntable, and a coil spring arranged between the turntable and the stopper. In a disk rotation mechanism including an elastically supported turntable center, a portion of the turntable fixed to the motor shaft is formed into a cylindrical shape, and the turntable center is vertically attached to the outer periphery of the cylindrical fixed portion. A disk rotation mechanism characterized in that the disk rotation mechanism is fitted so as to be slidable and rotatable in the circumferential direction.
