  • Patent number: 9472994
    Abstract: The present invention provides an AC generator for a vehicle, in which a resin case (26) includes convex portions (33) formed on an outer circumferential surface of the resin case (26) so as to extend in an axial direction of the resin case (26) to be brought into pressure-contact with an inner circumferential wall surface of a counter drive-side bearing housing portion (24), and convex portions (34) formed on an inner circumferential surface of the resin case (26) so as to be opposed to the convex portions (33). The concave portions (34) allow displacement of the convex portions (33) in a radially inward direction of the resin case (26). By an elastic force generated by the displacement of the convex portions (33), the resin case (26) is integrated with the counter drive-side bearing housing portion (24).

  • Patent number: 8212441
    Abstract: 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.
