In a combine travel transmission device in which the side clutch is connected and connected by a hydraulic cylinder using lubricating oil in a transmission case inside the transmission mechanism, the lubricating oil is usually returned from the hydraulic cylinder to the transmission case in a return circuit. A filter is provided to filter this lubricating oil, but a mounting member is required to mount this filter in an appropriate location, and in order to configure a return circuit, a hydraulic pipe and filter are required to communicate the hydraulic cylinder and the filter. It requires a hydraulic pipe to communicate with the inside of the transmission case, and it also requires many connecting members to connect these, so it is not economical due to the large number of components, and the structure tends to be complicated. .
