    摘要: In an alternating-current generator, an end wall of a frame is provided with a plurality of fin supports separately arranged on the outer surface of the end wall. The cooling fin is mounted on the plurality of fin supports. The end wall is provided with a plurality of reinforcements each arranged between a corresponding one of the plurality of fin supports and another one thereof and each configured to reinforce a rigidity of a portion of the end wall. The corresponding one of the plurality of fin supports and another one thereof are adjacent to each other in a circumferential direction of the axis of the rotor. The rigidity-reinforced portion of the end wall is located between the corresponding one of the plurality of fin supports and another one thereof.

    摘要: In an AC generator for a vehicle, an end cover has two types of parts, one-type part is away from a rib part in a positive cooling fin, and the other-type part is close to the rib part. The rib part projects toward the end cover side. The one-type part is thinner than the other-type part in the end cover in order to reduce the variation of thermal expansion in each part of the end cover. This configuration increases anti-thermal fatigue of the end cover.

    摘要: An alternator for a vehicle is provided which is equipped with a rectifier. The rectifier includes a positive-side radiator fin in which a positive rectifying device is installed. An output terminal through which dc voltage is outputted has a rectangular head and is fit in a through hole formed in the positive-side radiator fin. Ribs are formed on the positive-side radiator fin across the through hole. The rectangular head of the output terminal is shaped to have two sides and a diagonal line. The diagonal line is longer than an interval between the ribs. The sides are located at a distance away from each other which is smaller than the interval between the ribs. Specifically, the ribs serve as stoppers on which corners of the head hits when excessive torque acts on the output terminal, thereby minimizing deformation of the positive-side radiator fin and undesirable rotation of the output terminal.
