Patent ID: 8901792

Claim:
A motor comprising: a motor portion; and a speed reducing portion, wherein the motor portion includes a brush holder, which holds a feeder brush for supplying power to a commutator fixed to a rotary shaft, the brush holder being provided at an open end of a metal yoke housing, through which open end rotation of the motor portion is outputted, wherein a gear housing is assembled to the open end of the yoke housing, wherein the speed reducing portion has a speed reducing mechanism located in the gear housing, the speed reducing mechanism reducing the speed of the rotation from the motor portion and outputting the rotation, wherein as seen in a direction orthogonal to an axis of the yoke housing, the commutator and the feeder brush are arranged outside the yoke housing, and wherein as seen in the axial direction, an outer end of the feeder brush is arranged outside an inner circumferential surface of the yoke housing, wherein the brush holder includes: a cover portion formed of an outer circumferential wall portion and a circular wall portion, the outer circumferential wall portion extending in the axial direction and covering an outer circumferential surface of the commutator, the circular wall portion being formed on an axial end of the outer circumferential wall portion and covering an axial end face of the commutator; and a brush box accommodating the feeder brush, the brush box extending outward in a radial direction from the outer circumferential wall portion of the cover portion, wherein, as seen in the axial direction, a radial direction outer end of the brush box is arranged outside the inner circumferential surface of the open end of the yoke housing.
