PURPOSE: A static driving device of an AC generator for a vehicle is provided to improve the durability of the AC generator itself and prevent the noise by constantly maintaining the rotational speed of the generator. CONSTITUTION: Variable means(3,4) are installed at pulleys(1,2). The variable means(3,4) are transmitted by a belt(5). The rotational speed of the AC generator is within the constant rotational speed, and thus the transmitting rate of the pulleys is regulated. The variable means are installed on one side of the pulley of the engine. The regulation of the transmitting rate is accomplished by using the centrifugal forces of the pulleys(1,2).
