PROBLEM TO BE SOLVED: To provide a structure of a radiator shroud capable of increasing the cooling capacity of a radiator 13 by streamlining the flow of air discharged from the rotating fan 11 to suppress the lowering of air volume passed through the radiator 13. SOLUTION: This shroud 15 installed on the air discharge side of the radiator 13 is narrowed toward the centrifugal flow type rotating fan 11 to form a cylindrical shape and comprises a surrounding part 17 so as to surround the rotating fan 11. A guide part 23 extending in the centrifugal direction of the rotating fan 11 is formed at the peripheral edge part of the surrounding part 17, a cylindrical part 19 having a diameter smaller than that of the surrounding part 17 and formed in a cylindrical shape is formed on the inside of the surrounding part 17, and the upper part of the cylindrical part is fixed to the wall surface of the shroud 15. Also, the lower part of the cylindrical part 19 is fixed by a fixing part 21 having an inner diameter equal to the diameter of the cylindrical part and an outer diameter equal to the diameter of the surrounding part 17.
