摘要： An engine generator is provided having an improved cooling effect realized by cooling air while ensuring a compact arrangement of components in a housing. The engine generator includes an engine 2, a generator 3, an inverter 4, a control device, a fuel tank 7, an air cleaner 16, a muffler 18, a radiator 6, and a housing 5 accommodating the foregoing components. The engine generator includes cooling air inlets 12 and 11 and a cooling air outlet 14 on sides of the housing 5 with a cooling air passage disposed between the inlets and outlet. The generator 3, the inverter 4, and the air cleaner 16 are disposed further upstream than the engine 2 along a cooling air passage. The fuel tank 7, the radiator 6, and the muffler 18 are disposed further downstream than the engine 2 along the cooling air passage. Ambient air is incorporated as cooling air into the housing 5 through the cooling air inlets 12 and 11, allowed to flow from an upstream toward a downstream of the cooling air passage, and discharged to outside the housing 5 through the cooling air outlet 14.
