PROBLEM TO BE SOLVED: To provide a combine harvester facilitated in normally controlling a tightening degree of a fastener which compresses an elastic member interposed between an outer end part of a roof and an outer end part of a cover at a sealing part for sealing the outer end part of the roof and the outer end part of the cover.SOLUTION: At a sealing part 67, there are provided an elastic member 68 interposed between an outer end part 48b of a roof and an outer end part 65b of a cover; a bolt 66 which is arranged to penetrate the elastic member 68 while stretching to the roof and the cover 65, and compresses the elastic member 68 by tightening the roof and the cover 65 so as to approach each other; and a boss member 69 through which the bolt 66 can be inserted, and which is inserted into the elastic member 68 along the penetration direction of the bolt 66 so as to determine the tightening limit of the bolt 66.SELECTED DRAWING: Figure 17
