ABSTRACT:
A motor vehicle AC generator including a rectifier in which a direct-fitting surface of a negative-polarity side cooling plate is brought closely into contact with a casing direct-fitting surface of a rear bracket and is fixedly tightened with a fitting screw with respect thereto. In addition, a silicone sheet is interposed between the cooling plate and the rear bracket in a state of being located within an intervening member accommodating groove made in the direct-fitting surface of the cooling plate so as to cover an area lying light under a diode except the peripheral bearing surface of the fitting screw. This construction forms an electric conducting portion at which the direct-fitting portion of the cooling plate and the casing direct-fitting surface directly come into contact with each other and further forms a thermal conducting portion at which the direct-fitting surface of the cooling plate and the casing direct-fitting surface come into contact with each other in a state where the silicone sheet is interposed therebetween.
