[Title of the invention) A threshing cylinder for a threshing device [Object] rib propose a threshing cylinder fir a threshing device of enhanced threshing performance and feeding performance to the backward by avoiding tangling of grain crops around the threshing teeth. [Solution) The problems are solved by providing a plurality of plates (60) including a plurality of threshing teeth (60A) provided at a distance to one another and in the axial direction of the threshing-cylinder axis (12), and by disposing the plurality of plates (60) at a distance to one another on the outer surface of the cylinder (61) in the circumferential direction.
