The magnetic disc is provided with a driving pin through hole (14), a driving arm receiving hole (17), and first (14a) and second (17b) thin-wall portions exposed in the through holes. The driving pin is inserted in the driving pin through hole, and the engaging member is inserted in the driving arm receiving hole to lock them onto the first and second thin-wall-portions to thereby loosely fit the driving arm in the magnetic disc.
