PROBLEM TO BE SOLVED: To prevent an external appearance from being impaired when efficient ly cooling a radiator with a cooling fan by arranging the cooling fan feeding air to the radiator side from an engine side between the engine and the radiator. SOLUTION: A cooling fan feeding the cooling air to a radiator 23R side from a front bank section 20F is arranged between the radiator 23R arranged on the right side of the front bank section 20F of a water-cooled engine E and the bank section 20F. The cooling fan 24 is shielded from the outside by the radiator 23R, and the radiator 23R can be efficiently cooled during a constant- speed travel and during the idle operation of the engine E without impairing an external appearance. Hot air is discharged to the outside from the radiator 23R on the right side, the thermal pollution on the accessory apparatuses arranged near the front bank section 20F of the engine E is effectively prevented, and the thermal effect on an occupant is reduced. |
