PROBLEM TO BE SOLVED: To generate down force by utilizing a fuel tank, a rear cowl and a rider. SOLUTION: The fuel tank 5, a driving seat 4 of a two-seater 3 and the rear cowl 7 are longitudinally arranged in this order, and left and right both sides of the fuel tank 5 and the rear cowl 7 are largely projected to side parts as projecting parts 8 and projecting parts 9. When the rider sits on the driving seat 4 in a state of gripping knees by rear side faces of the fuel tank 5, the projecting parts 8 are approximately continued to the knees 36. The projecting parts 8 and the projecting parts 9 are respectively formed as forwardly inclined faces approximately in parallel with each other to allow the travel wind to be obliquely upwardly and backwardly escaped on their surfaces to generate the down force. |
