A streamlined cover that is installed on the driver's cab roof of a land vehicle equipped with a towed body for the purpose of reducing aerodynamic drag. It has a lower part, a rear part, and a nose part, and has a continuous contoured outer surface extending in the width direction and upward direction from the nose part toward the rear part, and an upper part and a side part connected at respective boundary lines. , the upper surface portion includes at least one substantially water-shaped arcuate portion, and the tangential surface of the arcuate portion has an inclination angle of tan with respect to the horizontal plane.
-1(2(H-h)X)≧Inclination angle to horizontal plane≧0°
, where H is the distance from the roof of the driver's platform to the upper wall of the towed vehicle body, h is the height of the streamlined canopy, and X is the distance after the streamlined canopy. The distance between the end and the front edge of the towed vehicle body, h, is 0.9H≦
h<H, and the side portion includes a generally perpendicular arcuate portion widened with respect to the longitudinal axis of the streamlined canopy, and a truncated surface of the arcuate portion is with respect to the longitudinal axis of the streamlined canopy. The inclination angle is equal to tan-1 ((W-w) / The width between the vertical arcuate portions, X is the distance between the rear end of the streamlined canopy and the front edge of the towing unit, W≧W≧0.
5W, and the horizontal arcuate portion is disposed at an uppermost position relative to the lower portion, and the vertical arcuate portion is disposed furthest relative to the longitudinal axis of the streamlined canopy; The land vehicle resistance reducing device is characterized in that the length l of the streamlined cover is equal to the length of the driver's roof≧1≧0.2W. 2. The device of claim 1, wherein the arcuate portion of the upper surface portion is substantially parallel to the horizontal line. 3. A request for registration of a utility model in which the relationship between the height h of the rectifier cover 70 and the vertical distance H from the driver's platform roof 71' to the upper wall of the towing vehicle body is 0.9H≦h≦1.2H. The device according to item 2 of the scope of the invention.
