A rotor bushing restrictor () that prevents a rotor bushing () from moving away from a stator () is provided. The rotor bushing restrictor () includes a fixing member () fixed on a body and a rotor bushing attitude retainer () placed between the rotor bushing () and the fixing member (). The rotor bushing attitude retainer () includes two first abutment portions () contacted with the rotor bushing () and two second abutment portions () contacted with the fixing member (). The two first abutment portions () are symmetrically placed to each other with respect to the axis of the spindle (), and the two second abutment portions () are symmetrically placed to each other with respect to the axis of the spindle (). The two first abutment portions () and the two second abutment portions () are placed such that a straight line connecting the two first abutment portions () and a straight line connecting the two second abutment portions () are orthogonal with each other.
