Abstract

A motor includes a housing, a back cover, a brush card, a brush, and a connector member. The back cover includes a first rear wall portion and a first peripheral wall portion. The first peripheral wall portion includes a through-hole and a cut-out. The through-hole vertically penetrates through the first peripheral wall portion at or near a lower end portion of the first peripheral wall portion. The cut-out is disposed farther on an upper side than the through-hole. The connector member is fitted into the cut-out. An outer surface of the connector member is provided with a flow path groove that extends in both peripheral and axial directions. The motor includes a flow path surface on an inner surface of the back cover. The flow path surface continues from a portion that opposes the flow path groove on a lower side of the flow path groove to the through-hole.
