<P>PROBLEM TO BE SOLVED: To provide a prime mover structure of a work vehicle capable of cleaning a substantially entire surface of a dust prevention net of a radiator, and enhancing the dust removing efficiency of dust deposited on the dust prevention net. Ž<P>SOLUTION: Radiator covers 2, 3 consisting of a net part (a net) 3 and a frame part 2 of the net part 3 are provided on the outer side of a radiator 5 for cooling an engine 16, and a wind blocking plate 6 having a moving mechanism 23 which is movable straight in the vertical direction of the net part 3 is provided along the net part 3 of the radiator covers 2, 3. The wind blocking plate 6 is reciprocated in the vertical direction of the net part 3, and when the plate is moved downward, dust deposited on the net part 3 below the wind blocking plate 6 is moved by the weight of the wind blocking plate 6 itself and the removing efficiency is enhanced. Further, when an air suction port 60 of an air suction passage leading to a cooling fan 1 by passing the radiator 5 is formed on a lower end of the net part 3, the dust collected to the lower side by the weight of the wind blocking plate 6 when the wind blocking plate 6 is moved downward is sucked from the air suction port 60 and removed to enhance the removing efficiency of dust or the like.
