PROBLEM TO BE SOLVED: To smoothly divide grain culms with a front side divider 21 and a rear side divider 22 from the front side divider 21 to the rear side divider 22 without relating to the lengths of the stranding grain culms and to the changes in the height of the reaping portion 3 on a lateral support axis. SOLUTION: This combine harvester in which the front side divider and the rear side divider are mounted in a mutually separated state, is characterized by gradually allowing the end portion of the front side divider from a position lateral to the entrance 5a of a threshing room to the rear portion to approach the frame so that the grain culms smoothly rearward flow, while the rear side divider is continuously formed from a front side inclined portion b1, a central parallel portion b2, and a rear side inclined portion b3 in this order in a state gradually approaching the frame to smoothly flow the divided grain culms. The front side divider and the rear side divider are positioned so that the end portion of the front side divider is superposed on the central parallel portion of the rear side divider in the plane view.
