By the way, in the combine, weight reduction of the fuselage is an important factor in the design from the viewpoint of improving wetland adaptability and the like, but weight reduction of the fuselage reduces rigidity of each part of the fuselage. There are certain restrictions to keep. In particular, the machine frame of the threshing unit is not easily deformed due to external force because the continuous opening is cut off on the three sides of the front and rear side plates and the outer plate to form the entrance and exit of the grain stem and the handle. The structure is easy to handle, and the front and rear side plates receive the rotational reaction force of the handle cylinder supported in the machine frame. It is necessary to obtain the wall thickness. Further, the same applies to a paddy processing unit such as a paddy tank which directly receives paddy weight, and particularly in the case of a large combine having a large paddy tank and a large vehicle height, the demand is strong.
