An object of the present invention is to provide a driving unit structure of a combine capable of performing a detachment operation with respect to a radiator of a vibration damping network by a simple operation and capable of exerting a vibration damping function satisfactorily. It is preferable that the side wall portion 38 of the circular portion has an appropriate mounting state in which the side wall portion 38 and the radiator 16 are brought into close contact with the radiator 16 in a state in which the vibration damping net 18 is interposed between the radiator 16 and the radiator 16, So that the vibration damping network 18 can be switched to the open state for opening the front side of the radiator 16 and the supporting frame 18 can be fixed to the frame body 52 of the rectangular frame shape provided on the outer peripheral portion of the intake side portion of the radiator 16 50 are fitted and fitted with a sealing material 55 which is elastically deformable over the entire periphery of the outer periphery of the frame body 52 and the side wall portion 38 is switched to the proper mounting state The side wall portion 38 presses the sealing material 55. In this state, An object of the present invention is to provide an operation device for a curved discharge auger in a combine, which makes it easy to perform an operation for instructing movement of the auger for discharge of the curved discharge. An instruction switch S for instructing a movement operation of the auger for discharge of the curled discharge is provided with an automatic switch 55 'for instructing an automatic turn for automatically turning the auger for discharging the curled product over the retracting position for retracting and the turning position for the curling discharge A turning position changing switch 56 'for instructing a position changing command for changing and setting the turning position for curled discharge, and a turning ascending / descending instructing means D for inst
