<p>An apparatus for installing a disk (1) having a through hole (2) formed in the center thereof, which comprises a rotatable shaft (10), a disk Support (13) which is fixed to the rotatable shaft (10) and has a supporting surface (13a) for supporting the one side of the disk (1), and a disk holder (14) which is detachably fitted to the rotatable shaft (10) and presses the disk (1) on its other side toward the supporting surface (13a), thereby to cause the disk (1) to be fixed between the disk holder (14) and the disk support (13). The disk holder (14) includes a holder body (15) which is provided to be fitted onto the rotatable shaft (10) and movable along the rotatable shaft (10), a pressure assembly (16) which is disposed on the holder body (15) to exert the disk (1) on its other side an elastic pressure against the supporting surface (13a), and a slip preventive mechanism (21) for preventing the holder body (15) from the rotatable shaft (10) by engaging the holder body (15) with the rotatable shaft (10) through the fitting of the holder body (15) onto the rotatable shaft.</p> |
