<P>PROBLEM TO BE SOLVED: To provide a combine harvester raising a suction wind velocity of a cross-flow fan according to simple constitution, and improving separation efficiency by winnowing in a separation part. Ž<P>SOLUTION: The separation part 130 includes: a winnower 132 disposed in front of the separation part 130 for feeding a separation wind to winnow a mixture which contains grains, passes from the upper part of a grain flow plate 135 through a chaff sieve 138 and a grain sieve 137, and falls into a first crop and a second crop; and the cross-flow fan 140 disposed behind the winnower 132 and at the rear of the separation part 130, covering the upper and lower rear thereof with fan casings 201 and 202, and covering the front of the fan casing 202 at the lower rear with a tong part 203 for sucking the separation wind from the winnower 132. The tong part 203 is formed over the full width of the cross-flow fan 140, and the gap between the tong part 203 and the outer periphery of the cross-flow fan 140 is extended.
