Patent ID: 7183682

Claim:
A motor comprising: a motor unit having a rotation shaft; an output shaft that is rotated by the motor unit; a speed-reducing unit that reduces a speed of rotation supplied from the rotation shaft and transmits the rotation to the output shaft; a control circuit board that controls the rotation of the rotation shaft; and a gear housing fixed to the motor unit, wherein: the gear housing includes a generally flat shaped speed-reducing unit receiving portion and a generally flat shaped circuit board receiving portion; the speed-reducing unit receiving portion receives at least a part of the speed-reducing unit; the output shaft extends outward beyond a side face of the speed-reducing unit receiving portion; the circuit board receiving portion receives the control circuit board; each of the speed-reducing unit receiving portion and the circuit board receiving portion radially extends from a center axis of the rotation shaft; a first fictive plane, which is associated with the generally flat shape of the circuit board receiving portions, is tilted away from a second fictive plane, which is generally parallel to the center axis of the rotation shaft and is generally perpendicular to an axis of the output shaft at a leading end of the output shaft; and a distance, which is measured between the first fictive plane and the second fictive plane in a direction parallel to the axis of the output shaft, increases in a direction radially away from the axis of the output shaft.
