摘要： A magnet disposed on the top face of an extended part of a bearing holding member has a semicircle shape as the maximum shaper and is disposed in the same direction as the movement direction of a disk dray in the circumferential direction. By the pulling force in the axial direction between the magnet and a rotor holder, the shaft tilts at an angle different from the gravity direction or a direction opposite to the gravity direction.

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.

摘要： Inner circumferential surfaces of a rotor holder and a turntable are in contact with an outer circumferential surface of a shaft. This stabilizes coaxiality of both the rotor holder and the turntable with respect to the shaft. An upper cover portion of the rotor holder includes fixing holes. The turntable includes fixing projections arranged to extend through the fixing holes to be in contact with a lower surface of the upper cover portion. A base end portion of each fixing projection is arranged at a level higher than that of an upper end portion of a corresponding one of the fixing holes. Therefore, even if dimensional errors of the rotor holder and the turntable cause a radial displacement between any fixing projection and a corresponding one of the fixing holes, the rotor holder and the turntable can be fixed to each other while maintaining coaxiality therebetween.

摘要： In a chucking device, a rolling guide portion is arranged below an upper cover portion of a rotor holder and radially inwards of a cylinder portion of the rotor holder. This helps restrain the noises generated by the rolling movement of balls from propagating to the outside. Moreover, the turntable and the rolling guide portion are formed of a single resin member extending continuously through a through-hole defined in the rotor holder.

摘要： A space for accommodating therein a portion of an optical pickup mechanism is arranged below a disk loading portion of a turn table member of a chucking mechanism of the present invention. The space is arranged axially below a disk mounting surface. Since such space is provided, a recording/reproducing portion will be allowed to move closer to a brushless motor, and therefore a second lens arranged further away from the brushless motor will be allowed to move radially inward of a recording/reproducing area of an optical disk.
