PROBLEM TO BE SOLVED: To avoid deficient husk treatment at a rear side of a threshing cylinder while suppressing increase of driving load at front side of the threshing cylinder.SOLUTION: There is provided a threshing part 3 provided with a threshing chamber 8 receiving a treating object from a front feeding port 8a and a threshing cylinder 11 placed in the threshing chamber 8 in a direction to direct a rotary shaft 15 in a longitudinal direction of the cylinder and threshing the threshing object according to rotary driving in a prescribed direction. The threshing cylinder 11 is provided with: a plurality of bar members 28 parallelly arranged in circumferential direction interposing specific gaps and a plurality of rod-shaped threshing teeth 10 protruding from the bar members 28 interposing a prescribed spaces in the direction of the rotary axis; the rod-shaped threshing teeth 10 contain rod-shaped threshing teeth 10A protruded outward from the threshing cylinder along the radial direction of the threshing cylinder and free from slant angle in rotational direction of the threshing cylinder and rod-shaped threshing teeth 10B having a slant angle in rotational direction of the threshing cylinder; and rod-shaped threshing teeth 10 positioned at a front side of the threshing chamber 8 are the rod-shaped threshing teeth 10B having a slant angle. |
