摘要： A chucking device includes a turntable fixed to a shaft having a central axis and a cone arranged axially above the turntable. An annular yoke is arranged above a sliding portion of the cone and fixed to the shaft, and a clamp magnet is fixed to the yoke through an adhesive agent. The yoke includes an upper surface having an annular recess defined in a concentric relationship with the central axis, the adhesive agent being applied on a region of the upper surface existing radially inwards of the recess. The recess includes a radial outer wall parallel to the central axis and a radial inner wall inclined radially inwards and axially upwards. The angle between the radial outer wall and a lower surface of the clamp magnet is greater than the angle between the radial inner wall and the lower surface of the clamp magnet.

摘要： A motor includes a chucking device to hold a disk having a central opening in a detachable manner. In the chucking device, a turntable part is arranged above a rotor holder and has a disk support surface for supporting the disk. An axially slidable cone part is arranged above the turntable part. A resilient member is axially arranged between the turntable part and the cone part upwardly biases the cone part. Further, the turntable part includes an inner table made of a metal and fixed to the shaft, and an outer table made of a resin material and fixed to an outside of the inner table. The outer table has the disk support surface and is axially spaced apart from the rotor holder in a position where the inner table and the outer table are fixed to each other.
