の油タンクに係る。 That is, this invention, in a work vehicle equipped with an engine 9 at the rear of the vehicle body 2, as in the embodiment shown, places the oil tank 1 for hydraulic circuit hydraulic oil at a position facing the radiator 5 at the rearmost part of the vehicle body 2. installed,
The oil tank 1 is characterized in that the inner wall 3 facing the radiator 5 is formed with an external structure that receives the cooling exhaust air 10 after passing through the radiator 5 and diverts the exhaust air 10 upward. Relating to oil tanks of work vehicles.

FIG. 1 shows the rear half of a wheel loader as an example of a work vehicle, and an oil tank 1 for hydraulic oil of a hydraulic system is provided at the rearmost portion of a vehicle body 2. As shown in FIG. As shown in FIG. 2, the shape of the oil tank 1 is such that its inner wall 3 is curved upward in an arc shape. Therefore, the oil tank 1 has an inner wall 3 as shown in FIG.
is arranged so as to face the radiator 5 , and when the engine 9 is driven, the engine fan 4 rotates, whereby exhaust air 10 passes through the radiator 5 and hits the inner wall 3 of the oil tank 1 .
is guided by the inner wall 3 and turns upward.
油タンク１の上方には、車体２に上部カバー６
