    • PROBLEM TO BE SOLVED: To improve cooling efficiency by a heat exchanger by preventing cooling air discharged from an exhaust port from being sucked again to an intake port when the intake port and exhaust port for cooling air are provided in a heat exchanger cover.
      SOLUTION: In the heat exchanger cover 17 covering the upper side of the heat exchanger 13, the intake port 21 is provided on the left side which is an upstream side of the cooling air, and the exhaust port 22 for discharging the cooling air passed through the heat exchanger 13 is provided on the right side opposite to the intake port 21. The exhaust port 22 has a configuration to discharge the cooling air to the horizontal direction above an engine cover 15. Thus, the cooling air passed through the heat exchanger 13 and heated can be discharged horizontally from the exhaust port 22 of the heat exchanger cover 17 toward the upper side of the engine cover 15. As a result, since the cooling air is discharged to the direction separate from and opposite to the intake port 21, this can prevent the heated cooling air from being sucked again to the intake port 21.

    • PROBLEM TO BE SOLVED: To enhance cooling efficiency by smoothly flowing cooling air from a cooling fan to an air-exhaust port, in a radiator system for small-vehicle in which a radiator is arranged on the side of crankcase constituting a part of an engine main body mounted on a car body frame having a water jacket, a cooling fan that sucks the cooling air so as to pass through the radiator is attached at one end of the crankshaft and arranged inside the radiator, and a shroud that covers the cooling fan from the side having the air-exhaust port is provided between the radiator and the crankcase. SOLUTION: A straightening vane 122 for inhibiting cooling air from a cooling fan 97 from flowing to a crankcase 21 side in a portion corresponding to an air-exhaust port 108, is fixedly disposed on the crankcase 21 side closer than the air-exhaust port 108 and the cooling fan 97.
