Power generator
In the power generator, an alternator driven by an engine to generate power, an inverter for the alternator, a fan to cool the engine, and a shroud via which air blown by the fan is guided to a periphery of the engine are stored inside of a casing. A fan cover that covers the alternator and the fan is provided in an end portion of the shroud, a ventilating opening is formed in an end portion of the fan cover, and an inverter supporter in which the inverter is installed is provided in a circumferential edge portion of the ventilating opening.
1. A power generator in which an alternator driven by an engine to generate power, an inverter for the alternator, a fan to cool the engine, and a shroud via which air blown by the fan is guided to a periphery of the engine are stored inside of a casing, wherein
a fan cover that covers the alternator and the fan is provided in an end portion of the shroud, a ventilating opening is formed in an end portion of the fan cover, and an inverter supporter in which the inverter is installed is provided in a circumferential edge portion of the ventilating opening, wherein
