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： A motor includes a turntable and a rotor holder unified with each other by insert-molding. The turntable includes a protrusion portion protruding radially outward beyond a cylinder portion and a substantially cylindrical covering portion extending downward from an radial inner end of the protrusion portion to cover an outer circumferential surface of the cylinder portion. The rotor holder has a radial outer end portion arranged in the same radial position as an outer circumferential surface of the covering portion or arranged radially inward of the outer circumferential surface of the covering portion. For this reason, a sliding contact area between a mold and the rotor holder is reduced. This helps suppress sliding contact between the mold and the rotor holder during a mold releasing process, consequently suppressing degradation of the mold.

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.

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.
