Abstract
In a generator in which a stator is fixed to a housing which includes a first bracket having a bearing portion for pivotally supporting one end portion of a rotary shaft, and a second bracket covering a cooling fan that rotates with the rotary shaft, and a rotor surrounded by the stator is fixed to the rotary shaft, the stator is fixed to the first bracket, and the first bracket is integrally provided with a tubular portion which surrounds the stator for permitting cooling air sucked in by the cooling fan to flow between the tubular portion and an outer periphery of the stator, and the second bracket is connected to the tubular portion. Accordingly, cost is reduced by connecting first and second brackets together without using long through-bolts, and efficiency of cooling the stator is enhanced by making the cooling air flow along the outer periphery of the stator.
