A motor has a motor unit, an output shaft, a speed-reducing unit for controlling the motor unit, a control circuit board and a gear housing. The speed-reducing unit transmits a rotation of the rotation shaft of the motor unit to the output shaft to rotate slower than the rotation shaft. The gear housing is fixed to the motor unit and includes a generally flat shaped speed-reducing unit receiving portion, which installs at least a part of the speed-reducing unit therein, and a generally flat shaped circuit board receiving portion, which installs the control circuit board therein. The output shaft protrudes beyond and perpendicularly to a side face of the speed-reducing unit receiving portion. The circuit board receiving portion is inclined to the speed-reducing unit receiving portion around a center axis of the rotation shaft to be retracted from an output shaft side of the speed-reducing unit receiving portion.
