PROBLEM TO BE SOLVED: To solve the problems wherein a device for remotely operating a conventional unloader cannot carry out the operation of an expandable auger by which the unloading auger can be expanded and contracted although the unloader can carry out each operation of right and left turning, upper and lower movement, or on- or off-operation of a grain-unloading clutch device. SOLUTION: The unloading auger 3 is constituted so as to unload grains stored in a grain tank 2 of a combine harvester 1. The unloading auger 3 is constituted so that the operation for expanding and contracting a grain-unloading opening 5 opened at the tip part of a transporting cylinder 4, the operation for regulating the height in the upper and lower direction, and the turning operation thereof may be operated by both of an operation device 6 installed in the combine harvester 1 and a remote control operation device 7 enabling the operation at a site separated from the machine body of the combine harvester 1.
