Abstract: A wiper motor including an electrically conductive housing in which a speed reduction mechanism is housed, a motor body housed within a yoke joined to the housing and having a power supply terminal that contacts a commutator so as to supply electric power to a rotor, and having a brush that includes a ground terminal having one end in contact with the commutator and another end connected to an electrically conductive partitioning wall of the housing that covers an opening in the yoke, a power supply line configured to supply electric power to the power supply terminal via a noise-suppression choke coil, a ground line connected to the partitioning wall and to ground, and a capacitor connecting the power supply line with the ground line, such that a noise component flowing through the ground line passes through the choke coil.

Abstract: The motor has a motor housing. The motor housing supports therein rotatably an armature having a rotating shaft and a commutator. Brushes are brought into friction contact with the commutator. The brushes have brush holders for holding them respectively. The brush holders are attached to a base plate having a first side and a second side. A plurality of electric parts are mounted on the base plate. These electric parts are allocated to the first side and the second side of the base plate.
