PROBLEM TO BE SOLVED: To provide a motor capable of attaining miniaturization, which has a rotor sensor, and in which a worm shaft is connected to a rotor rotary shaft via a connecting member, such as a clutch. SOLUTION: This motor is provided with the rotating shaft 6, supported and driven rotatably by a yoke 4, the worm shaft 23 supported by a gear housing 21 so as to be coaxial with the rotating shaft 6, the clutch C connecting the rotating shaft 6 and the worm shaft 23, transmitting the rotation from the rotating shaft 6 to the worm shaft 23, and blocking the transmission of the rotation to the rotating shaft 6 from the worm shaft 23, and a rotating sensor S, having a Hall IC 15 which, is fixed to a sensor magnet 51 fixed to integrally rotate with the rotating shaft 6, the yoke 4, and the gear housing 21, and detects the rotational speed of the magnet 51. The sensor magnet 51 is fixed to a shaft part 32a of a drive-side rotor 32 of the clutch C connected, so as to rotate integrally rotor with the rotating shaft 6. |
