A magnet 34 for the rotating shaft (first magnet, second magnet) is installed on the extended portion of the rotating shaft 33b in the gear housing 41, and Hall ICs 65a to 65c for the rotating shaft (first sensor, second sensor) are formed on the control board 60 inside the gear housing 41 so as to face the magnet 34 for the rotating shaft. The Hall ICs 65a to 65c for the rotating shaft are adapted to detect the rotation position of the rotating shaft 33b relative to the stator 32, that is, the rotation position of the rotor 33 relative to the stator 32, and the Hall ICs 65a to 65c for the rotating shaft are adapted to detect the rotation number of the rotating shaft 33b.
