A portable generator includes a metal shroud surrounding at least a crankcase and a cylinder block of an engine. The engine is directly mounted to the shroud. The shroud forms an effective radiating element and gives an additional heat-radiating surface to the engine, thereby increasing the heat radiation capacity of the engine. Heat generated from the engine while running can, therefore, be radiated efficiently. The shroud is mounted within a sound insulating case, so that the portable generator has a double sound-insulating structure. The noise-proofing property of the portable generator is, therefore, very high.
