  As described above, when the engine bonnet is swingable in the open position in a state separated from the cabin, if the holding force in the closed position of the engine bonnet is weak, rattling due to running vibration or the like tends to occur. Become.

  In the case of the above-described prior art, a tightening force is strongly applied to an engine bonnet or an air supply case constituted by a plate body that is not so thick, and the engine bonnet tends to be unstable depending on traveling vibration and driving vibration. In addition, since it is difficult to expect rigidity at the connecting portion, it is necessary to strengthen the support of the cabin in other portions.

  An object of the present invention is to provide a combine having a connecting portion that can hold an engine bonnet in a closed position so as not to rattle and can support a cabin.

The combine according to the present invention is:
A cabin covering the driving part;
An engine provided in an engine room located below the operating unit;
It is possible to swing between a closed posture that covers the engine room located below the cabin, and an open posture that opens on the lateral side of the fuselage while being separated from the cabin. An engine bonnet that is supported and provided with an air supply case that is located outside the body of the engine room and is capable of introducing outside air into the engine room;
A coupling mechanism that couples the engine bonnet in the closed position and the cabin; and
Of the side walls of the cabin, the side wall structure adjacent to the upper side of the air supply case in a state where the engine bonnet is in the closed posture is configured to swing together with the engine bonnet,
The connection mechanism connects the side wall structure and a cabin structure other than the side wall structure in the cabin.

  According to this configuration, the engine bonnet is held in the closed position by applying the holding force by the coupling mechanism to the side wall structure that is not easily deformed as compared with the engine bonnet and the air supply case, so that relatively strong running vibration and drive vibration Even if this occurs, deformation of the side wall structure is difficult to occur, and rattling of the engine bonnet is unlikely to occur. Further, since the connecting portion has rigidity, the connecting portion can support the cabin.

  Therefore, according to the present invention, since the engine bonnet is less likely to be rattled, the operating part can be made in a comfortable state and the overall cabin support structure can be simplified.

  In the present invention, it is preferable that the cabin structure is a part of the side wall that is adjacent to the upper side of the side wall structure in a state where the engine bonnet is in the closed position and does not swing together with the engine bonnet. is there.

  According to the present invention, the side wall structure can be made smaller and the swing operation of the engine bonnet can be lightened as compared with the case where the entire side wall is adopted as the side wall structure that swings together with the engine bonnet.
