PROBLEM TO BE SOLVED: To inhibit an increase of threshing load due to grain culm.SOLUTION: A threshing cylinder of a threshing device that has a cylindrical body (61) supported by a threshing cylinder shaft (12) in a threshing chamber (10) is provided with multiple plates (60) that respectively have rod-like threshing teeth (60A) arranged at intervals in an axial direction of the threshing cylinder shaft (12), and the plates (60) are arranged with intervals between each other on an outer peripheral surface of the cylindrical body (61). The plates (60) comprise a first plate (18) equipped with first threshing teeth (18A) and a second plate (19) equipped with second threshing teeth (19A), and the first plate (18) and the second plate (19) are arranged alternately on the outer peripheral surface of the cylindrical body (61). Each installation interval of the second threshing teeth (19A) of the second plate (19) is set to be larger than that of the first threshing teeth (18A) of the first plate (18). |
