PROBLEM TO BE SOLVED: To provide a combine harvester capable of lightening a load by a friction mechanism installed in an interlock mechanism when the unexpected load is given to a tip unloading cylinder because when a shock load is transmitted to the interlock mechanism connected to the tip unloading cylinder, a risk of damaging a pivotally supporting part and a gear meshing part of the interlock mechanism is present. SOLUTION: The combine harvester is constituted as follows: the tip unloading cylinder 69 is freely turnably installed in the end terminal part of the auger cylinder of an unloading auger 14 through a spindle, and the end terminal opening part of the unloading auger 14 is opened and closed by the upper and lower turning of the tip unloading cylinder 69 by the interlock mechanism R installed between an output shaft from an electrically driven motor 70 for driving the unloading cylinder, and the tip unloading cylinder 69. A friction mechanism F is installed between turning positions in the interlock mechanism R of the tip unloading cylinder 69 to absorb the load given to the tip unloading cylinder 69 from the exterior.
