PROBLEM TO BE SOLVED: To provide a combine harvester designed to keep at constant levels the tension on a conveyor equipped in a feeder housing caused by the revolution of the feeder housing at an inflection point to mitigate the burden on the conveyor, thereby effecting the smooth conveyance of reaped grain culms and increasing the degree of freedom of the revolving angle and shape of the feeder housing. SOLUTION: In the combine harvester where a conveying unit 9 is designed to be revolvable at the inflection point 89 provided midway of a conveying path, the conveying unit 9 comprises the conveyor 11 and the feeder housing 10 internally equipped with the conveyor 11, and the inner circumference of the conveyor 11 at the inflection point 89 is provided with a guide rotator and the outer circumference a press rotator for putting the trajectory of the conveyor 11 in compliance with the guide rotator. As an example, there are provided two tension rollers for pressing the conveyor 11 and these tension rollers are joined to each other via a tension rod 55 and made to interlock with the revolution of a supporting shaft 75 as the revolving support of the feeder housing 10.
