Abstract: A rising temperature of components of an electric generator is restrained without deteriorating the quality of electricity output and the user-friendliness of the electric generator. AVR (7) and a temperature detecting means (75) is provided in a generator housing. While the detected temperature is greater than the limitation starting temperature, the output voltage is decreased by decreasing the control target value (for the AVR (7)) in accordance with the temperature. A range between the power generation stopping temperature as an upper-limit temperature of a generator component and the limitation starting temperature set to be a lower than the power generation stopping temperature is defined as a voltage droop range. In the voltage droop range, the control target value is decreased in accordance with a target voltage base value preset in a relationship with the temperature so that the decrease degree becomes greater in proportion to a rising temperature.
