摘要： A holder-side connecting portion 10c provided on a brush holder 10 and a connector-side connecting portion 16b provided on a connector portion 16 are electrically and mechanically connected with each other. The holder-side connecting portion 10c and the connector-side connecting portion 16b are clamped between a yoke housing 4 and a gear housing 21. For this reason, the connecting portions 10c and 16b for connecting the brush holder 10 and the connector portion 16 are prevented from being externally exposed. As a result, the insulation of the connecting portions 10c and 16b can be secured without complicating the construction of the connecting portions 10c and 16b by applying a special seal or the like to the connecting portions 10c and 16b.

摘要： A motor includes a motor portion and a speed reducing portion. In the motor portion, a brush holder that holds a feeder brush for feeding electric power to a commutator is arranged at an opening of a yoke. The speed reducing portion has a speed reducing mechanism, which is arranged in a gear housing. The speed reducing mechanism outputs drive force produced by a rotary shaft of the motor portion with the rotating speed of the rotary shaft reduced by the speed reducing mechanism. A brush holder includes a support pillar projecting toward the gear housing and an urging member that urges the feeder brush against the commutator. A positioning portion for positioning the brush holder with respect to the gear housing in a direction perpendicular to the axial direction is formed at a distal end portion of the support pillar.

摘要： Each of a plurality of brushes is tilted relative to an imaginary plane that is perpendicular to a rotational axis of an armature and is placed on one axial side of a brush holder, at which an interior of a yoke housing is located. A radial inner end part of each brush has a slide contact surface, which is generally parallel to the rotational axis of the armature and slidably contacts an outer peripheral surface of a commutator. At least a portion of the slide contact surface of each brush is axially disposed outside of an opening of the yoke housing.

摘要： A gear housing accommodates a worm shaft. A brush holder includes a base member and a retaining member loosely fitted to the base member. The base member is located between the gear housing and the retaining member. The retaining member retains a first brush and a second brush. The retaining member has a pair of positioning poles, and the gear housing has a pair of positioning projections. The positioning poles and the positioning projections are engaged with each other so as to prevent the retaining member from being moved in a direction perpendicular to the axial direction of the rotary shaft.
