PROBLEM TO BE SOLVED: To provide a grain threshing device having an improved efficiency of threshing operation by easily conducting maintenance in such a space of the threshing device, especially a feed opening 11, that is easily plugged during the threshing operation. SOLUTION: This grain threshing device conducts threshing treatment so that culms of which the total amount is fed from the feed opening 11 positioned on a front wall 10 of a threshing chamber 2 are backward transferred by a threshing drum 1 located and axially supported in the inside of the threshing chamber 2, wherein a threshing net 3 located in a lower peripheral area of the threshing drum 1 is divided into two of the right and left parts by an area of the net which positions intermediately between the left and right sides of the feed opening 11 and spreads in a direction perpendicular to the opening. And, either 3 of the right and left parts 3, 3 of the threshing net which is divided into the two parts is so structured that the part can be outward swung to be opened.
