To provide a motor with a speed reduction mechanism for reducing an adverse effect due to heat generation of wound wires.
A rotor 41 is disposed inside a stator 22 fixed to the inner peripheral surface of a yoke housing 21. In a gear housing 51 fixed to an opening of the same yoke 21, a reduction mechanism 63 is disposed which reduces a rotating force of the rotor 41 and outputs the reduced rotating force from an output shaft 64. A bus bar unit 31 is disposed in the gear housing 51, and in the gear housing 51, a first sensor magnet 46 rotating integrally with a rotary shaft 42 of the rotor 41 is located at a position shifted from a bus bar unit 31 in the axial direction of the rotary shaft 42, and disposed at a position further from the stator 22 than the bus bar unit 31. A first magnetic sensor 71 facing the first sensor magnet 46 outputs a first rotation detection signal corresponding to the rotation of the rotary shaft 42. In the gear housing 51, a first connector is formed to connect an external connector for extracting the first rotation detection signal from an output terminal.
