Abstract:
An electric motor comprising:a motor main body that includes a rotatable shaft, which is rotated upon energization of the motor main body; a speed reducing unit that is connected to the motor main body and includes: a speed reducing mechanism that reduces rotational speed of the rotatable shaft; and a gear housing that receives the speed reducing mechanism; and a circuit board that is held in the gear housing and has a circuit, which controls rotation of the rotatable shaft of the motor main body, wherein: the gear housing includes a circuit board receiving portion, which opens toward the motor main body and receives the circuit board; the motor main body further includes a brush holder, which supports a plurality of power supply brushes and includes a motor-side connector to be connected with an external connector, wherein the motor-side connector is integrated into the brush holder; the circuit board is installed to the brush holder in a direction perpendicular to an axial direction of the rotatable shaft to electrically connect between the motor-side connector and the power supply brushes; and the circuit board is received in the circuit board receiving portion when the motor main body and the speed reducing unit are assembled together.
