Patent 7380869 was granted and assigned to Toyota on June, 2008 by the United States Patent and Trademark Office.
An aerodynamic device for a vehicle has, within a wheel house in which a front wheel is disposed, a movable liner portion which can, along a vehicle longitudinal direction, approach and move away from a vehicle longitudinal direction front side portion of the front wheel. When a traveling speed of a vehicle exceeds a predetermined speed, a lower portion of the movable liner portion approaches the front side portion of the front wheel. An aerodynamic device for a vehicle is obtained which can suppress flowing-in of air into a wheel house accompanying traveling of a vehicle.
