Abstract
A motor includes a motor unit and a speed reducing unit. The speed reducing unit has a gear housing. The gear housing includes a circuit board receiving portion and an opening that faces the motor unit. A control circuit board is received in the circuit board receiving portion through the opening in an axial direction of a rotatable shaft. When the motor unit is assembled to the speed-reducing unit, the control circuit board is clamped between the speed-reducing unit and a cover connected to the motor unit.
