A duct is arranged within the engine room, for guiding air flow having passed through the radiator, to the outside of the engine room without exposure of the air flow to the engine. At least a part of the exhaust muffler connected to the engine is disposed within the duct so that the exhaust muffler is cooled by at least a part of the air flow guided by the duct. Preferably, the engine is a vertical type V-engine.
