PROBLEM TO BE SOLVED: To increase velocity of an air stream led into the direction of the rear face of a vehicle by a spoiler device of the vehicle to scatter a foreign matter adhered to the rear face of the vehicle as much as possible. SOLUTION: This spoiler device for the vehicle consists of a back door outer 3 provided turnably in a rear end part of a roof panel 2 of the vehicle 1, a back door window 4 adhered closely and fixed to the back door outer 3, a rear spoiler 5 mounted on the back door outer 3 to streamline fluid (air), and a projecting part 6 provided at a position just before the rear spoiler 5 and in an upper end part of the back door outer 3. The projecting part 6 has a curve shape having a radius of curvature R1 and a projection amount h1 from a reference face 3b of the back door outer 3. When the vehicle 1 runs, velocity of air stream along the roof panel 2 is increased by the projecting part 6, and accelerated air stream is streamlined by the rear spoiler 5 and is supplied for the back door window 4. Consequently, the accelerated air stream scatters the foreign matter adhered to a surface of the back door window 4.
