摘要: A brush holding device includes a dielectric resin circuit board and at least one metal brush holder secured to the circuit board at its base portion. Each brush holder includes a receiving recess that receives a brush and a spring for urging the brush against a commutator. A side wall of the brush holder located at a radially outer side of the brush holder includes an engaging piece that resiliently engages against an inner peripheral surface of an outer peripheral wall of the circuit board.
