A motor (6) connecting with an antivibration spring (7) is received in a motor housing (9). The antivibration spring (7) is constructed of a radial supporting portion (51) and a thrust supporting portion (52) that are integrally formed. The radial supporting portion (51) resiliently holds a radially side face portion of the motor (6) in the radial direction. The thrust supporting portion (52) resiliently holds an axially end face portion of the motor (6) in the axial direction. Vibration of the motor (6) in the radial direction is damped by the radial supporting portion (51), and vibration of the motor (6) in the thrust direction is damped by the thrust supporting portion (52), even when a motor housing (9) vibrates in both the radial and the thrust direction of the motor (6). Thus, vibration-proofing performance of the motor (6) can be significantly enhanced. |
