PROBLEM TO BE SOLVED: To simply compose a structure of shaking and driving of the lower side and upper side parts with an actuator when the lower side part of an auger is freely shakingly supported in the lower part of a grain tank and the upper side part of the auger is composed so as to freely bend relatively to the lower side part of the auger in the middle part of the auger in an auger structure of a combine harvester. SOLUTION: There are provided an actuator freely shaking and driving the upper side part of the auger 15 in a housed state and a state of use and connecting mechanisms 39a and 40 connecting the upper side and lower side parts 17 and 16 of the auger in the state of use. The upper side part 17 of the auger 15 is shaken and driven in the state of use with the auger 15. The auger 15 is composed so as to be freely shaken and driven with the actuator 33 in the state of the upper side and lower side parts 17 and 16 of the auger 15 connected in the state of use by means of the connecting mechanisms 39a and 40. An artificial operation tool artificially operated by operating and performing the stop operation of the actuator 33 is installed in or near a drive part. COPYRIGHT: (C)2004,JPO&NCIPI
