The invention discloses a front wing reverse adjusting device for a formula car. The front wing reverse adjusting device comprises a flap and a main wing. The flap is fixedly connected with a car frame through extending pieces. The axis of the flap is perpendicular to the length direction of the car frame. The main wing is suspended below the flap through elastic telescopic pieces, and the telescopic direction of the elastic telescopic pieces is set to be the vertical direction. By the adoption of the front wing reverse adjusting device, the small ground clearance of the main wing is guaranteed when the formula car moves at a constant speed, meanwhile, in the formula car braking process, the phenomenon that the main wing nods along with the car frame is prevented, and the situation that the whole front wing makes contact with the ground, consequently the front wing is damaged, and even a racing driver is hurt is avoided.
