The present invention relates to a deflector for responding a vehicle speed including a deflector body installed at a door frame to rotate diagonally toward the rear of the vehicle, wherein one end of the deflector body in the front of the vehicle is connected via a hinge and the other end thereof in the rear of the vehicle is configured in a form of a free end; a solenoid connected to the deflector body and pushing up or down the deflector body; a piezoelectric element installed in a division channel and sensing the intensity of wind being in contact with the same; and an ECU adjusting a projection height of the deflector body in multiple levels by applying control current corresponding to three levels to the solenoid on the basis of the vehicle speed, a status of a rear door glass, and a sensing signal of the piezoelectric element.
