PROBLEM TO BE SOLVED: To provide a combine harvester having an openable and rotatable reaping part, wherein the bracket device supporting the reaping part when the reaping part is opened and rotated is formed to have light and strong structure. SOLUTION: The combine harvester has a bracket device 29 rotatably supported on a perpendicular spindle 31 stood on a machine frame 30, by which bracket device 29 a first cylinder body 17 is rotatably supported. The bracket device 29 has bushes 37, 38, arms 43, 44, an end plate 45 and a bearing element 46, and reinforcing plates 52 are fixed on front and rear both surfaces of the upper and lower arms 43, 44. In a state that the reaping part is not opened and rotated, the free end of the bracket device 29 is fixed on a support 47. When the reaping part is opened and rotated, the second cylinder 19 is supported by a stopper 56. As the upper and lower arms 43, 44 are hollow and attached with the reinforcing plates 52 on the front and rear both surfaces, so the arms have a light and strong structure.
