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 (25) is fixed to the first bracket (22), and the first bracket (22) is integrally provided with a tubular portion (22b) which surrounds the stator (25) so as to permit cooling air sucked in by the cooling fan (29) to flow between the tubular portion (22b) and an outer periphery of the stator (25), and the second bracket (23) is connected to the tubular portion (22b). Accordingly, it is possible to reduce cost by connecting first and second brackets together without using long through-bolts, and to enhance efficiency of cooling the stator by making the cooling air flow along the outer periphery of the stator. |
