Abstract
A chucking device in a floppy disk drive comprises a rotor yoke adapted to rotate in a predetermined certain direction with a center hub of a floppy disk placed thereon, a drive pin mounted loosely into a drive pin through hole formed in the peripheral portion of the rotor yoke and further inserted loosely into a drive pin aperture formed in the center hub, and a spring mounted to the rotor yoke and functioning to push the drive pin not only upward but also in a direction F away from a rotational axis of the rotor yoke. When the rotor yoke is rotated with the floppy disk placed thereon and with a center shaft inserted into a central aperture of the center hub, the drive pin is inserted into the drive pin aperture and comes into abutment, within the drive pin aperture, with both front edge and outer edge of the same aperture in the rotational direction of the rotor yoke.
