Patent Number: 6,528,912

Title: Automotive alternator

Abstract: An automotive alternator secures a fastening force for a vehicular connecting terminal for an extended period of time, and restricts the axial displacement of an output terminal, thus ensuring higher reliability. The output terminal is press-fitted and secured in a through hole in a first cooling plate, and the takeout end thereof is drawn out of an opening of a rear bracket. A metal bush is loosely inserted in an insulating bush and externally fitted to the output terminal, and the vehicular connecting terminal is fasteningly secured to the metal bush by a nut. With this arrangement, the fastening force of the nut is received by the rear surface of the first cooling plate via the metal bush. A flange of the metal bush is positioned so that a gap is provided between the flange and the insulating bush. The axial displacement of the output terminal is restricted by the flange abutting against the insulating bush.
