Abstract
An automotive alternator mounted on a vehicle for generating electric power includes front and rear frames, a cylindrical stator and a rotor. The cylindrical stator is contained in the frames, and the rotor is rotatably supported in the cylindrical stator. A rectifier device for rectifying alternating current generated in the stator into direct current is mounted on a rear surface of the rear frame and covered with a rear cover. To sufficiently cool minus rectifier elements positioned at a place not easily cooled only by the outside cooling air introduced into the alternator, a base portion of the minus rectifier element is contacted to the rear frame thereby to establish heat conduction therebetween. A resilient heat-conductive member is disposed between the base plate and the rear frame to absorb any dimensional discrepancies therebetween.
