An engine generator includes an engine, a generator coaxially connected to the engine, a soundproofing case, and an exhaust muffler. The soundproofing case is divided into three, that is, a chamber to be cooled, and engine-side and generator-side air intake chambers on opposite sides of the chamber to be cooled. The chamber to be cooled houses the exhaust muffler and the majority of the engine and generator. Ventilation pathways are formed between an exhaust vent, which is provided in an upper part of the soundproofing case so as to open into the chamber to be cooled, and engine-side and generator-side outside air inlets which are provided in the soundproofing case so as to open into the engine-side and generator-side air intake chambers. Air is taken into the two air intake chambers from outside the soundproofing case via the two outside air inlets flows through the chamber to be cooled, and is discharged via the exhaust vent to the outside.
