Abstract

PURPOSE:To prevent the external force applied to an output terminal from being transmitted directly to a rectifier cooling fin so as to prevent the deformation or the damage of the rectifier cooling fin by providing insulating bushes between a flange part, a bracket, and a output terminal mounting nut, and then fastening the output terminal mounting nut. CONSTITUTION:A flange part 7 is provided at an output terminal 3, and an output terminal mounting nut 10 is fastened with insulating bushes 8 and 9 between, Whereby the output terminal 3 is fixed to a bracket 1. After the output terminal mounting nut 10 is fastened, a nut 6 is fastened, whereby a positive side rectifier cooling fin 2 and the output terminal 3 are fixed. Since the output terminal 3 is fixed to the bracked 1 in advance, even if external force is applied to the output terminal 3, it prents the extermal force from being transmitted to the positive side rectifier cooling fin 2. Hereby, the generator can be assembled without the bracket and the output terminal interfering with each other which results in the marring of the assembling property.
