In a traveling work vehicle installed with another hydraulic pump 10 driven by the pump shaft 8 of the pump 5, an oil filter 11 equipped with oil supply ports 12, 13 at both front and rear ends is installed in the lower part of the mission case 2. The front end of the filter is fitted and held in the support hole 15 on the mission case wall through the insertion hole 14 at the rear end of the mission case, and the filter is removably attached to the back of the mission case using the mounting flange 16 at the rear end. , an oil supply passage 17 for the charge pump 7 is provided in the plate member 3;
An upper side connection passage 18 communicating with 7 and a lower side connection passage 19 communicating with the above-mentioned bearing hole 15 are formed in the front wall of the mission case 2 by opening on the outer surface of one side of the front wall. The connection passages 18 and 19 on the upper side and the lower side are connected between the outer surface of one side of the transmission case and the side plate 2 to which the axle case 20 of the rear wheel axle 1 is mounted on the outer surface of the transmission case.
A vertical communication path 22 formed between the inner surface of
and an oil supply port 13 at the rear end of the oil filter is connected to the other hydraulic pump 10 by an oil supply pipe 23.
