Kind Code:
B2
Abstract:
The invention includes a stator (2) disposed inside a yoke (4), an armature (8) supported inside the stator (2), a commutator (7) connected to the armature and having a sliding surface (34) in an outer peripheral portion, and a brush (9) disposed opposing the commutator (7) and having a sliding contact surface (35) that comes into sliding contact with the sliding surface (34) of the commutator (7), wherein the brush (9) has a first member (9b), and a second member (9a) with an electrical resistance value higher than that of the first member, the first member (9b) is disposed on an entrance side and the second member (9a) on an exit side with respect to a direction of rotation of the commutator (7), and the sliding contact surface (35) of the brush (9) is such that an inclined portion (19) that inclines toward the entrance side with respect to the direction of rotation of the commutator (7) is formed in the first member (9b).
