It was difficult to reduce noise.

The present invention solves the above-mentioned conventional drawbacks by attaching left and right fixed frames to the outside of the rear cover of the threshing machine via hooks, installing front and rear slide guides between the fixed frames, and installing a binding transmission case. The unit is slidably engaged and supported by each of the slide guides at a position below the focusing space, and the lower part of the bundled transmission case is partially inserted between each of the slide guides, and the bundled transmission case is attached and detached. In some cases, the slide guide and fixed frame can be easily attached and detached integrally with this, and the lower part of the bundled transmission case is inserted between the front and rear slide guides to support the front and rear of the case, which is more convenient than before. The supporting structure of the bundled transmission case can be simplified to reduce mechanical vibration and work noise, and slide guides installed in front and rear of the bundled transmission case below the entire convergence area can be connected to the protective bumper at the bottom of the case and the above-mentioned. It can be used as a frame member for transportation when the case is removed, and in particular, each of the fixed frames and each slide guide is configured in a rectangular shape in a plan view so that the tied transmission case is located in the center, The center of gravity of the case can be easily located, and the horizontally movable bundled transmission case can be stably erected and supported while preventing back and forth vibration.
