PROBLEM TO BE SOLVED: To suppress the suction of bubbles generated in oil with the stirring operation of a transmission gear of a harvester, from suction ports provided in an oil pan. SOLUTION: A transmission case 8 splittable into two right and left parts is formed into a tank for operating oil serving as lubricating oil. An oil path for sucking the operating oil is formed on a mating surface between the right and left case parts 8A of the transmission case 8. The suction ports 54 of the oil path are arranged deviating from side to side to be the farthest possible from a rotating member of the transmission gear, thus suppressing the suction of the bubbles generated by the rotating member.
