<p>A body 40 is positioned above an area between front and rear wheels 1a and 1b; 2a and 2b. Wings 10 and 11 for generating a down force F to increase the load of wheels upon the ground by an air stream flowing from the front side to the rear side are provided between the front wheels 1a and 1b and between the rear wheels 2a and 2b, respectively. Flow paths 41 and 43 along which an air flows from the front side to the rear side during forward travelling to the wings 10 and 11 are defined in and along the body 40. <IMAGE></p> |
