ABSTRACT:
An engine generator can have an engine duct for releasing to the outside a cooling air which is used to cool an engine and a muffler, and a generator duct for releasing to the outside a cooling air which is used to cool a generator. The engine duct and the generator duct can be formed in one body as an exhaust duct. The muffler and the generator can be laterally aligned in parallel with each other, and the engine duct and the generator duct can be located in a manner such that the directions of release of the cooling winds from the engine duct and the generator duct are parallel to each other. The exhaust duct can be located with the generator duct secured to a crankcase. An opening of the engine duct, and an opening of the generator duct can be laterally aligned with each other, and the opening of the generator duct can be positioned above the generator.
