Abstract:
To provide an air-cooling type oil cooler for a vehicle which is improved in a cooling effect, the air-cooling type oil cooler having an intake port at a rear face side of the vehicle and an exhaust port at a lower face side, and arranged in a portion other than a front part of the vehicle.SOLUTION: A speed increase member 32 is arranged at a front side of an exhaust port 20b of an air-cooling type oil cooler 20 of a vehicle 10. By this constitution, exhaust-port side pressure P1 in the exhaust port 20b in the case that the speed increase member 32 is not arranged can be reduced to exhaust-port lower pressure P3, and a difference between the intake-port side pressure P2 and the exhaust-port side pressure is increased.
