する作業用走行車における冷却フアン構造。 Tension belts for forward rotation and reverse rotation that rotate the cooling fan placed on the back of the radiator in the forward and reverse directions are tensioned in opposite directions, and are linked together to selectively rotate the cooling fan in the forward and reverse directions. In terms of mechanism, the belt tensioning mechanism for reverse rotation changes the intermediate pulley around which the tension belt for reverse rotation is suspended from a relaxed state to a tensioned state by pressing the tension belt into contact with the cooling fan side pulley. A work vehicle characterized in that the intermediate pulley is configured as a movable intermediate pulley that moves to a position where the belt is tensioned, and the intermediate pulley that has moved to the belt tensioning side overlaps a mounting member for attaching a cooling fan in the air blowing direction. Cooling fan structure.
