ABSTRACT:
A compact engine-operated generator unit having a high soundproof effect in which a generator thereof can be cooled efficiently as well as an engine and a muffler thereof. The engine-operated generator has an engine and a generator driven by the engine arranged in a row with a common rotary axis and accommodated in a soundproof case. The generator, the engine and the muffler are arranged in order within the soundproof case and covered by a duct to be isolated from other instruments in the soundproof case; the duct has an end on the side of the generator opening to an interior of the soundproof case and another end on the side of the muffler opening to an exterior of the soundproof case; and a cooling fan is driven by the engine so that air in the soundproof case is inhaled through end opening of the duct on the side of the generator into the duct, sequentially cools the generator, the engine and the muffler in order and then is discharged through the end opening of the duct on the side of the muffler to the exterior.
