摘要： A chucking device for a magnetic disk that includes a substantially disk-shaped bearing and a drive arm extending in a rear side of a rotor yoke along a circumferential direction and loosely suspended from and held by a rotor yoke on both ends. An inner peripheral surface for restraining movement toward a bearing is formed at the drive arm, and a drive pin loosely passing through a drive pin through hole of the rotor yoke to extend upward and loosely inserted into a drive hole of a magnetic disk is formed at a front part of the drive arm in a rotor yoke rotation direction. When the rotor yoke having the magnetic disk placed thereon is rotated, the inner peripheral surface of the drive arm comes away from the bearing, and the drive pin comes in contact with a front edge and an outside edge of the drive hole.

摘要： A base of an arm having a driving projection at its tip is rotatably supported on a turn table. The turn table is provided with a first guide part and a second guide part, an outer edge part of the base of the arm and a first guide part are in contact with each other at a contact point, and a projection and a second guide part are in contact with each other at a contact point. While the arm rotates in a counterclockwise direction, the contact points are moved, and it is possible to prevent the center of the driving projection from largely deviating from a reference normal. Thus, even if a hub in which the position of the driving hole is shifted is mounted, the hub is not largely shifted in a rotation direction relative to a turn table.
