る。The main body 11 of the rear spoiler 1 is located along the rear edge 31 of the vehicle roof 3 and has a rectangular opening 14 at two right and left sides in the vehicle width direction on its plate surface. FIG. 2 shows a cross section of the main body 11 of the rear spoiler 1. The rear spoiler 1 is formed in a hollow thick plate shape by blow molding of a resin material or the like, and is fixed to the upper edge frame 22 of the back door 2 by embedding bolts 15 provided on the lower surface.

部が位置している。The upper surface 1a of the rear spoiler 1 is a concave curved surface that curves downward, and its front edge is the rear edge 31 of the vehicle roof.
And is smoothly connected to this in close proximity to the upper surface of the. The rear edge of the upper surface 1a of the curved rear spoiler 1 is raised upward, but the height of the front end of the rear spoiler 1 is sufficiently large relative to the total height H of the vehicle. The opening 14 is formed to penetrate obliquely rearward near the bottom of the upper surface 1a of the rear spoiler formed in a concave curved surface, and the upper portion of the rear window glass 21 is located below the opening 14.

汚れや雨滴の付着が防止される。In the rear spoiler having such a structure,
The airflow flowing along the vehicle roof 3 flows along the downwardly curved upper surface 1a of the rear spoiler 1. At this time, a downward pressing force acts on the rear spoiler 1 to reduce the rear lift of the vehicle. At the same time, a part of the airflow flowing along the vehicle roof 3 decreases at the bottom of the upper surface 1a and the pressure increases, and as a result, as shown by a white arrow in FIG. The dynamic pressure is converted to static pressure. Then, the rear window glass 21 whose pressure is reduced as the vehicle travels
Due to the pressure difference from the vicinity of the rear window glass 21, the air flow is largely changed downward and blows toward the glass surface of the rear window glass 21, and thereafter, the airflow flows downward at high speed along the glass surface to form an air curtain. Such an air curtain prevents dirt and raindrops from adhering to the glass surface of the rear window glass 21.

る。(Second Embodiment) Rear edge 31 of vehicle roof 3
Is formed into a smooth curved surface extending to the rear window glass 21, the shape of the main body 11 of the rear spoiler 1 may be as shown in FIG. That is, in FIG. 3, the central portion of the main body portion 11 except for both side edges is cut rearward in a rectangular shape, and this cutout forms an opening 16 penetrating toward the upper edge of the lower back window glass 21. ing. Then, the airflow flowing along the vehicle roof 3 hits the rear inner wall 161 of the opening 16,
Rear window glass 2 which can be turned greatly downward
Air is blown toward the glass surface of No. 1 to form an air curtain.
