A rear air spoiler 4 is attached to the rear end of the vehicle to generate downward aerodynamic force and prevent the rear of the vehicle from lifting due to lift force.

FIG. 2 shows a first embodiment of the invention.

In this embodiment, an electric window washer 5 for the rear window is included in the rear air spoiler main body 40.

The rear air spoiler main body 40 has a substantially model-like cross-sectional shape, and the inside is made of a lightweight molded material such as soft urethane foam, and the outer surface is made of a tough surface material such as dense 14-1 knotane. The main body 40 has a lower surface 41 which serves as a barrier to the vehicle body, and is formed at an acute angle with respect to the lower surface via a leading edge 42 so as to form an angle of attack with respect to the airflow flowing along the surface of the vehicle body. A front surface (upper surface) 43 which is an aerodynamic force generation surface for generating downward aerodynamic force (corner lift), and a pair () to the aerodynamic force generation surface 43 via a trailing edge 44 to ensure airflow separation. A horizontally elongated 4Il with a triangular cross section consisting of an acute-angled back surface 45! Winged? do.

In this embodiment, the electric window washer 5 is provided in the main body 40 and has a removable cap 511 (one inlet 51
