Zusammenfassung:An automotive alternator is provided that has a brush holder assembly that reduces exclusive circumferential space for the brush holder assembly inside a rear bracket, and that also reduces entry of water, dust, etc., into a regulator circuit housing portion. The brush holder assembly has a base and a plate. The base is prepared by molding a brush holder portion, a regulator circuit housing portion, and a connector portion integrally, and the plate is mounted to the brush holder portion, and has a cover portion that closes the resin injection aperture of the regulator circuit housing portion. The brush holder portion, the regulator circuit housing portion, and the connector portion are formed so as to be positioned such that respective center lines thereof are in a common plane that includes a central axis of the rotating shaft. A lead-through opening that is formed on the rear bracket so as to allow the connector portion to be led through is generally closed by the connector portion and the cover portion.
