Abstract
An air deflector blade for vehicles and the like is pivotally movable between a substantially vertical orientation and a substantially horizontal orientation in response to the wind velocity created thereupon. The pivotal mounting enables the blade to rotate selectively between the vertical and horizontal positions in proportion to the speed of the vehicle.
