Abstract
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.
