(51) Can be separated from each.

The operation member 82 may be formed to have a polygonal shape. Accordingly, in the threshing apparatus for a combine according to the present invention, when compared to the comparative example in which the operation member 82 is formed to form a circular shape, the operator uses an operation tool (not shown) such as a monkey spanner. It may be implemented so that the adjustment unit 8 can be easily operated. Therefore, the threshing device 1 for a combine according to the present invention can improve the ease of operation of the operation of the control unit (8).
