ABSTRACT:
Each of the paired brush devices includes a brush in sliding contact with a commutator, a brush arm holding the brush, and a brush base to which the brush arm is fixed and which has a base hole. The pair of brush devices are disposed such that a line connecting the centers of the pair of brushes inclines in relation to a line connecting the centers of a pair of magnets. Each of the brush arms of the brush devices is disposed on the outside of the corresponding brush base at a location where the brush arm is fixed to the brush base, and one of the brush arms is bent from the outside of the corresponding brush base toward the inside thereof while being passed through the base hole to intersect the brush base.
