To provide a threshing section for combine which reduces grain loss during threshing work and improves with improved threshing performance.
SOLUTION: A threshing drum (31) of a threshing section (30) for a combine is provided with first threshing teeth (313) arranged along a first helix 301 which is coaxial with the threshing drum 31. The threshing drum is also provided with second threshing teeth arranged at positions which are adjacent in the front-rear direction to the first threshing teeth. The first threshing teeth and the second threshing teeth are arranged such that the first and second threshing teeth are displaced from each other in the front view. In a concave 32, sieving body-forming members (322A) of a sieving body (322) are rotatably supported ON a frame body (321). Intervals between adjacent sieve body forming pieces in the curved direction of the sieve body is set in such a way that the adjacent sieve body forming pieces are not simultaneously opposed to the tip parts of each of the threshing teeth adjacent in the longitudinal direction of the threshing cylinder in the front view of the threshing cylinder.
