Abstract A brush holder adapted for automatic assembly having a simplified construction and reduced cost. The brush holder is composed of a generally U-shaped holder box having an opening extending from a top end thereof along one side of the box, and a holder plate covering the opening. The holder plate has a recess for receiving the brush therein, and a stop for preventing movement of the brush through the opening of the holder box when retained by the stop. When the brush is to be mounted on a motor casing or the like, a protrusion of the motor casing is extended through a through-hole in the holder plate, thereby releasing the brush from engagement with the brush stop and permitting it to protrude through the hole in the top end of the box.
A brush holder comprising: a generally U-shaped holder box having an opening extending from a top end thereof along one side thereof; and a holder plate covering said opening of said holder box, said holder box having a brush stop at an inner surface of a top end thereof for holding a brush in said holder box, said holder plate having a through-hole therein for receiving a protruding member for releasing said brush from said brush stop to permit said brush to protrude from said holder.
