PROBLEM TO BE SOLVED: To provide a threshing apparatus solving the problems of threshed grain cloggings at the terminal end of a threshing chamber and of declining in the efficiency of exhaust dust transfer into an exhaust dust treatment device. SOLUTION: The threshing apparatus has the following construction: A threshing chamber 12 with a threshing net 18 set up at the bottom of a threshing cylinder 11 is installed. A swing separator 23 is set up beneath the threshing chamber 12. The flank of the rear of the threshing chamber 12 is equipped with an exhaust dust treatment device 30 communicating, via the exhaust dust communicating port 33 on the rear of the threshing chamber 12, with the threshing chamber 12 and axially mounted with an exhaust dust treatment cylinder 31. The rear end of the threshing chamber 12 is provided with a threshed grain discharge port 40 via which threshed grains that do not drop via the threshing net 18 are discharged. The threshed grain discharge port 40 is provided with a filter 42 having many discharge holes 41, wherein the filter 42 is composed of a transverse frame 45 crossed with a longitudinal frame 44 parallel to the axial direction of the threshing cylinder11 and plates 46 provided on both left and right sides of the longitudinal frame 44 and the transverse frame 45, with the top rim of the transverse frame 45 projected above that of the longitudinal frame 44.
