ことを特徴とする電動モータにおける刷子の仮保
持構造。 An electric motor in which a brush is urged to protrude from a brush holder and come into sliding contact with a commutator,
The brush holder is provided with a wall portion having a protrusion formed on the inner surface and elastically deformable in the direction of the rotor axis, and a hole portion corresponding to the protrusion is provided on the outer surface of the brush to resist the urging force. The brush inserted into the brush holder is temporarily held in the retracted position by releasably engaging the hole and the protrusion, and the wall part is fitted with a yoke to temporarily hold the brush in the retracted position. The yoke is elastically deformed by a wall pressing means provided on the yoke,
1. A structure for temporarily holding a brush in an electric motor, characterized in that the structure is configured to change into a temporary holding release position.
