Abstract
An engine generator comprises a fan cover made of die-cast aluminum alloy, and a power control unit including an aluminum base sheet. The base sheet has a power control circuit formed thereon. The fan cover includes a mounting portion to be attached to the power control unit. When the power control unit is attached to the fan cover, a surface of the aluminum base sheet comes into intimate contact with an outer surface of the mounting portion. Heat generated at the unit is transmitted to the fan cover, and then released from the fan cover serving as a heat releasing member.
