A brush holder device includes a brush including an integrally formed engagement portion; a brush arm having an engagement hole formed therein, the engagement hole assuming substantially the same shape as that of the engagement portion of the brush, and including brush contact portions located at laterally opposite edges of the engagement hole; and a holder. The holder has an engagement hole formed therein, the engagement hole assuming substantially the same shape as that of the engagement portion of the brush, and is fixedly attached to the brush arm such that the engagement hole is aligned with that of the brush arm. The engagement portion of the brush is press-fitted into the engagement holes of the holder and the brush arm, which are fixedly attached to each other, to thereby be fixed in place.
