PROBLEM TO BE SOLVED: To solve a problem that since a conventional threshing machine has such a constitution that there is almost no difference between the rotating peripheral speeds of a threshing cylinder spanned with a shaft at the interior of a threshing chamber and a dust-discharging treating cylinder spanned with a shaft at the interior of the dust-treating chamber, or the rotating peripheral speed of the threshing cylinder is made higher than that of the dust-discharging treating cylinder in order to improve the threshing performance, in the threshing machine, there is a tendency of lacking the smoothness in the flow of a series of discharged dusts and incapable of treating in a high efficiency. SOLUTION: This threshing machine constituted by connecting the beginning end of a dust-discharging and treating chamber 4 spanning a dust-discharging and treating cylinder 3 with a shaft in its interior at the rear part of a threshing chamber 2 spanning a threshing cylinder 1 with a shaft in its interior, is provided by setting the rotating peripheral speed of a dust-discharging and treating drum higher than that of the threshing cylinder 1.
