PROBLEM TO BE SOLVED: To facilitate moving operation and maintenance operation of a threshing device especially by devising the structure for moving the threshing device based on an undercarriage frame in a combine harvester. SOLUTION: The combine harvester has the threshing device 4 installed in the upper part of an undercarriage frame 1, and the threshing device 4 is constituted so as to be freely moved from the operation position at the upper part of the undercarriage frame 1 to a nonoperation position at which a part or the whole of the threshing device 4 is removed from the upper part of the undercarriage frame 1 based on the undercarriage frame 1. The undercarriage frame 1 has an assistant frame 45 for supporting the threshing device 4 from the lower part, and installed so as to be freely advanced and retreated based on the undercarriage frame 1.
