PROBLEM TO BE SOLVED: To perform the thresh-treatment of cereal culms having a good threshing property smoothly while suppressing the formation of straw dusts. SOLUTION: This threshing device is provided by installing a threshing drum 11 rotating around a threshing drum shaft in front to rear direction at the inside of a threshing chamber 10, a secondary treating chamber 15 in which a secondary treating drum 16 attached with a non-continuous treating teeth rotating around a shaft in front to rear direction is built-in at the one side of left and right of the threshing chamber 10, a discharged dust-treating chamber 18 in which a discharged dust-treating drum 19 attached with the continuous treating teeth is built-in at the rear direction of the secondary treating chamber 15 and a swinging sorting shelf 29 in the lower direction of the threshing chamber 10, secondary threshing chamber 15 and discharged dust-treating chamber 18. And on arranging threshing teeth 12 on the outer circumferential surface of the threshing drum 11, the threshing teeth 12 are arranged so that the lower side of the rotation inclines in backward sending direction against the rotational direction of the threshing drum 11, and the inclining angle in the backward sending direction is constituted as larger than the inclining angle in the backward sending direction of threshing teeth 12 of front side part of the threshing drum 11.
