PROBLEM TO BE SOLVED: To provide a threshing apparatus capable of smoothly unloading waste dust to the outside even when the large amount of materials to be treated such as straw wastes is unloaded from a waste dust treating chamber. SOLUTION: The threshing apparatus includes the waste dust treating chamber 68 axially installing a waste dust treating cylinder located at the under rear of a threshing chamber axially installing a threshing cylinder having a threshing tooth, and having a helical tooth for separating grains from the materials which are transported from the threshing cylinder to be treated, and cutting and treating the materials to be treated other than the grains, and comprising members containing a ceiling wall surface 72 and a lower receiving net. The helical diameter of a rear treating tooth 71a2 is reduced from the helical diameter of a treating tooth 71a1 on the front side in the helical teeth, and a plurality of protrusion-like treating teeth 71a' are mounted on the rear treating tooth 71a2. A plurality of cutting teeth 71c are installed on the upper tilt side of the ceiling surface 72 of the waste dust treating chamber on the side opposite to the receiving net disposed under the waste dust treating cylinder so as not to overlap with the protrusion-like treating teeth 71a'.
