ABSTRACT:
An air deflector apparatus for trucks is adjustably moveable between a lower position substantially parallel to the top of a truck cab, and an upraised position providing streamlined flow of air up over the trailer. A pneumatic cylinder is employed and brace arms or struts operated thereby support the weight and force of the deflector such that the cylinder is not called upon to provide the supporting force.
