Abstract
The spindle motor includes a rotating shaft, a rotor cover which is secured to the rotating shaft and rotates the rotating shaft, a bearing for rotatably supporting the rotating shaft, a holder for holding the bearing, and a holding magnet which is directly mounted to an inner wall of the rotor cover. In this case, the holding magnet is positioned above the bearing to prevent oil from being discharged from the bearing to the outside.
