摘要： A motor includes a bearing mechanism, a stationary unit including a stator arranged radially outwards of the bearing mechanism, and a rotary unit supported by the bearing mechanism at the upper side of the stationary unit for rotation about a center axis with respect to the stationary unit. The rotary unit includes a substantially cylindrical closed-top rotor yoke having a cover portion arranged to cover the stator. The bearing mechanism includes a substantially cylindrical closed-bottom bush formed by a press work, a sleeve fixed inside the bush and provided with an upper portion protruding beyond the bush and a shaft inserted into the sleeve. An upper end of the bush is lower than or flush with an upper end of the stator in a direction parallel to the center axis.

摘要： A motor includes a stationary unit, a bearing mechanism, a rotary unit, and a chucking device. The rotary unit includes a rotor yoke provided with a cover portion extending around the chucking device and designed to allow the storage disk to be directly or indirectly mounted thereto and a removal-preventing member fixed to the cover portion to prevent removal of the rotary unit from the stationary unit. The removal-preventing member made of metal. The removal-preventing member includes a removal-preventing portion, an upper fixing portion having a plurality of upper protrusions inserted into the through-holes of the cover portion and bent toward the upper surface of the cover portion, and a lower fixing portion making direct or indirect contact with the lower surface of the cover portion and cooperating with the upper fixing portion to fix the position of the removal-preventing portion in a direction parallel to the center axis.
