Zusammenfassung:PROBLEM TO BE SOLVED: To simplify a lubricating oil supply structure to a travelling system hydraulic switch unit and a PTO clutch unit stored in a mission case capable of reserving oil and to supply the lubricating oil to one of the units that tends to be short of the lubricating oil. SOLUTION: The transmission is provided with a common lubricating oil line connected to a hydraulic source by fluid connection and a first and second lubricating oil lines corresponding to the respective units arranged in an upper part and a lower part. The first lubricating oil line is connected to the common lubricating oil line at an upstream side in a lubricating oil flow direction from a second lubricating oil line by the fluid connection and a throttle is interposed in the common lubricating oil line between a connecting point with the first lubricating oil line and a connecting point with the second lubricating oil line.
