ABSTRACT:
A chucking device, in which a 31/2" flexible disk is centered and driven so as to rotate, is improved. A driving pin is disposed on one end of a plate spring and the other end portion is elastically energized to be brought into contact with a plurality of holding pins disposed on a turn table so as to protrude therefrom. At the chucking, since the plate spring is separated from the holding pins, sliding resistance, wear, etc. are not produced. For this reason, even if the chucking is repeated over many years, a high centering precision can be sustained.
