PURPOSE:To surely clamp a disk to a spindle mechanism by providing a bearing member to plural hangers and guiding the moving of the clamper hanger in depressing the clamper in parallel with the surface of the disk. CONSTITUTION:A disk 16 is loaded from the direction of arrow to a disk drive and a lever 10 is operated, then a lever shaft 11, a swing arm 12 and a clamper hanger 13 are moved in interlocking with the lever 10. The clamper 14 is moved to the spindle mechanism by the operation of the clamper hanger 13 to clamp the center wheel of the disk 16 to the spindle shaft 17 of the spindle mechanism. Since the clamper hanger 13 is guided by plural hanger bearings 21, 22 and moved toward the spindle mechanism in parallel state, the clamper hanger 13 depresses the clamper 14 toward the spindle shaft 17 direction and the clamper 14 clamps the disk 16 surely to the spindle shaft 17 without any gap with the spindle shaft 17.
