Abstract
A brush assembly applied to a motor includes a body portion attachable to a lower case, and an external connection substrate formed by a flexible substrate. A pair of brush pieces protrude from a front end of the body portion so as to be in contact with brush slide portions of commutator segments. The external connection substrate has a pair of terminals exposed from a housing and capable of being connected to spring terminals of an apparatus by crimping. The terminals are provided at a rear end of the external connection substrate, and protrude from the housing in the radial direction. First connecting portions electrically connected to the brush pieces are provided at a rear end of the body portion, and a pair of right and left second connecting portions are provided at a front end of the external connection substrate.
