PROBLEM TO BE SOLVED: To provide a combine harvester where a reaping part is horizontally turnable around a vertical support shaft 21, designed to improve the supporting strength of the vertical support shaft 21 and a machine frame on the reaping part while suppressing the increase in the number of parts. SOLUTION: The combine harvester has the following construction: The vertical support shaft 21 and a second beam member 72b are joined to each other via a turning support frame 80 inclined so as to lower in height as it sets apart from the vertical support shaft 21. The extending direction of the frame 80 is set in such a direction that the included angleθ, seen from the top, made by the frame 80 with an imaginary line VL extending from the vertical support shaft 21 to the center of gravity G of the reaping part 3 expands from an acute angleθ1 to an obtuse angleθ2 as the reaping part 3 is put to open turning.
