PURPOSE:To allow the running air that flows at a higher position from a road surface and does not contain dirt and dust comparatively to flow into an internal combustion engine side and improve the cooling efficiency by forming a cooling air flow path between covering plates provided at both front sides of a car body. CONSTITUTION:An exhaust tube 16 is connected to the front side of the cylinder 12 of an internal combustion engine 8 and passes through the lower part of the engine 8 and then is stretched to the rear. A pair of covering plates 18 is provided at the front side of the car body so as to cover both sides of the car body at the symmetrical location and a cooling air flow path (A) is formed between these covering plates 18. The covering plates 18 are stretched up to the lower part of a radiator 10 along a down tube 5 and cover both sides of a front fork 4 from the upper front of the engine 8. Besides, the covering plates 18 are extended to the front of the fork 4 and a headlight 19 is mounted on its tip. At high speed running, cooling air flows into the engine 8 side from the cooling air flow path (A) formed between a pair of covering plates 18. |
