Abstract
A brush holder having brush holding portions and coil holding portions is disclosed. Each brush holding portion holds a brush such that the brush is slidable on a commutator attached to a rotary shaft. Each coil holding portion holds a choke coil electrically connected to one of the coils. The brush holder includes a holder base member and brush holding members that are assembled to the holder base member so as to form the brush holding portions. Each brush holding member includes a coil supporting portion, which forms the coil holding portion between the corresponding brush holding member and the holder base member.
