DISK CLAMPING DEVICE

PURPOSE:To simplify a clamp spring and to stabilize an interval between a clamper and a clamper holding part at the time of clamping by providing a stopper metal fitting separately from the clamper and transmitting clamp force through the metal fitting at the time of clamping. CONSTITUTION:A clamper pressing spring 2 is fitted to a holding part 6 and a stopper metal fitting 1 is also fitted to the holding part. When a disk is clamped, the clamp force is transmitted from the pressing spring 2 to the disk by the metal fitting 1 and accordingly, the interval is made stable between the flange of a clamper 5 and the clamper holding part 6. When the disk is ejected, since the clamper 5 is pressed to the holding part 6, the backlash of the clamper 5 is not generated in the holding part 6.
