Abstract
An alternating current generator has a cooling function for a vehicle and includes a front bracket and a rear bracket with annular recessed portions that form a peripheral cooling chamber. A cooling cover is provided on the rear bracket. The cooling cover and the rear bracket form a rear cooling chamber. The peripheral cooling chamber and the rear cooling chamber are connected together through a connecting hole provided in the rear bracket. The front and rear brackets also form a parts housing chamber for receiving electric parts. The parts housing chamber is isolated from the peripheral and rear cooling chambers so as not to accommodate the fluid.
