PROBLEM TO BE SOLVED: To provide a combine harvester in which threshed products transported and sent out from the upper side of a grain-flowing plate to the upper side of a chaff sieve are separated with separation air guided from the sub-separation air port of a winnower, thereby accelerating a shaking and transporting action to efficiently separate the threshed products. SOLUTION: The winnower 35, a main separation air route disposed between the grain sieve for separating the grains leaked down from a grain sieve 44 and a first conveyer 10 and for guiding the separation air from the winnower, and a sub-separation air route disposed on the grain sieve and used for guiding separation air toward the starting end portion of the chaff sieve are disposed on the lower side of a shaking separation device 15 which has the grain-flowing plate 40 for receiving, shaking and transporting the threshed products and simultaneously leaking down and separating the grains, the chaff sieve, and the grain sieve 44.
