A deflector apparatus for regulating air flows at a rear of a vehicle, comprising:
- a movable portion arranged at a rear of a roof panel and an upper of a rear window of a vehicle and extended in a vehicle width direction, the movable portion movable to increase and decrease a protrusion amount of a front end portion of the movable portion in a vehicle front-rear direction from an upper surface of the roof panel to upward;
- and
- a driving system for driving the movable portion to decrease the protrusion amount as a vehicle speed increases to decrease an amount of air introduced by the movable portion and flowing along the rear window, the driving system for driving the movable portion to increase the protrusion amount as the vehicle speed decreases to increase the amount of air introduced by the movable portion and flowing along the rear window;
- wherein at the same vehicle speed, the movable portion is set so that the protrusion amount during deceleration of the vehicle is less that the protrusion amount during acceleration of the vehicle.
