PROBLEM TO BE SOLVED: To provide a threshing device for performing a selection in a state that the straw dusts leaking and falling down from a shaking selection device are hardly mingling with recovered cereal grains from a first screw conveyer. SOLUTION: This threshing device is provided with a wind-blowing guide 40 extending from a wind passage 35 of a fan case 31 of a fanning mill 30 to the vicinity of an upper part of the first screw conveyer 25. The wind-blowing guide 40 acts as a guide for a selection wind from the fanning mill 30 so as to cross the first screw conveyer 25 and flow in rear direction. COPYRIGHT: (C)2003,JPO
