Abstract
A motor includes a cylindrical rotor housing that contains a rotor, a brush holder mounted to an opening of the rotor housing, an end plate, having an electrically conductive part, which holds the brush holder in between the end plate and the rotor housing, and a grounding mechanism that realizes a ground connection to both a part of wiring led to a brush, provided in the brush holder, and the end plate. The grounding mechanism is provided in a region where the brush holder faces the end plate.
Claims8
A motor comprising:
- a cylindrical yoke housing that contains a rotor;
- a brush holder mounted to an opening of the yoke housing;
- a cover member that holds the brush holder in between the cover member and the yoke housing, the cover member having an electrically conductive part;
- and
- a grounding mechanism that realizes a ground to both a part of wiring led to a brush, provided in the brush holder, and the cover member,
- wherein the grounding mechanism is provided in a region where the brush holder faces the cover member, and
- wherein the grounding mechanism is configured such that a conductive biasing member, provided on one of the brush holder and the cover member, biases an electrically conductive part provided on the other of the brush holder and the cover member.
