Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a seat support that supports a driver's seat, a side cover that covers a lateral side of the living space of the driver, and an operation lever guide that is supported by the side cover. A rear outer wall portion and a top plate portion that are located on the opposite side of the side cover from the side wall portion, the rear side wall portion, and the front side wall portion. It is related with the operation part structure of the combine comprised so that it may form in the state to do.
[0002]
[Prior art]
In the above-described combine, conventionally, the seat support base and the operation lever guide are prepared as separate parts and assembled to the driving unit.
[0003]
[Problems to be solved by the invention]
Since the operation lever guide is disposed near the driver's seat so that the operation lever can be easily operated, the operation lever guide and the seat support base are assembled in a state of being adjacent to each other. For this reason, even when the operation lever guide and the seat support are assembled in contact with each other, a gap is easily formed between the operation lever guide and the seat support due to the manufacturing accuracy and the like. As a result, conventionally, for example, when an engine is installed below the driver's seat and the seat support base is used for the engine bonnet, the engine drive sound and heat dissipation generated in the driving section are driven from between the operation lever guide and the seat support base. Troubles such as leaking into the living space of the club were likely to occur.
