ABSTRACT:
A construction machine includes an engine guard, an engine, a cooling fan, and a device for being cooled by the cooling fan, and an exhaust duct. The engine guard accommodates the engine and has intake and exhaust openings. The intake opening and the exhaust opening are disposed in different side covers. The side covers correspond to the left and right side walls of the engine guard. The engine, the cooling fan, and the device are accommodated in the engine guard. The exhaust duct is disposed above and behind the engine, parallel with the flow of a fan air which has been used for cooling the engine, and substantially horizontally. The exhaust duct has an exit connected to the exhaust opening. The fan air introduced from the intake opening flows substantially linearly along the cooling fan, the engine, and the exhaust duct and is discharged from the exhaust opening.
