PROBLEM TO BE SOLVED: To provide a compact threshing device having improved selection efficiency of a material to be treated by improving an installed position of a blast guide member installed in an outlet part of air for selecting the threshed material to be treated. SOLUTION: Grains are dropped while swinging the material to be treated, including the grains after being threshed in a threshing chamber 66 for separating the grains from grain culms by a swinging shelf 51, and the dropped grains are selected by blowing the air by dividing the air from a fan 79a for selecting the material to be treated by the air, and installed in the lower part of the swinging shelf 51 into a main stream F1 and a sub stream F2 by an air-divider 92, and further dividing the divided air by an air guide 93 installed in the swinging shelf 51 positioned at the upstream side of the air passage of the divided air. As a result, the flow rate of the selection air based on a sieve 53 is not changed too much to make the selection good because the air guide 93 is moved with the swinging shelf 51.
