The engine generator includes cooling air inletsandand a cooling air outleton sides of the housingwith a cooling air passage disposed between the inlets and outlet. The generator, the inverter, and the air cleanerare disposed further upstream than the enginealong a cooling air passage. The fuel tank, the radiator, and the mufflerare disposed further downstream than the enginealong the cooling air passage. Ambient air is incorporated as cooling air into the housingthrough the cooling air inletsand, allowed to flow from an upstream toward a downstream of the cooling air passage, and discharged to outside the housingthrough the cooling air outlet
