Abstract
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.
