PROBLEM TO BE SOLVED: To provide a combine harvester capable of reducing noises of engine sounds in the outside of a machine without deteriorating the heat balance of an engine room, preventing lowering of the flow rate of cooling air and efficiently cooling the engine without causing defective screening of wet grains, etc. SOLUTION: This combine harvester is provided with a screening part equipped with a winnower fan for screening and separating threshed grains and waste straws by wind force near the engine room. In the combine harvester, an axial-flow fan is installed on the side of the engine room of the axis of the winnower fan. The engine room is a nearly closed space provided with an inlet port and a lead-out port for passing the cooling air from a radiator through the engine room and a hollow passage may be installed for transporting the cooling air from the lead-out port to an intake port for the open air of the winnower fan.
