Aerodynamic device for a motor vehicle, comprising a flap (2) movable between an extended position and a retracted position, a rotating actuator, and a transmission mechanism coupled to the actuator and configured for transmitting the movement of the actuator to the flap (2). In the event that the flap (2) receives an impact when said flap (2) is arranged in the extended position, the aerodynamic device is configured for preventing the actuator and/or transmission mechanism from being damaged. To that end, the flap (2) comprises a fixed portion (20) coupled to the transmission mechanism, and a mobile portion (21) coupled to the fixed portion (20) in a manner that is movable between a normal operation position and an emergency operation position, and the aerodynamic device comprises an over-center spring (5) coupling the fixed portion (20) and the mobile portion (21) of the flap (2) and exerting a force on the mobile portion (21) such that said mobile portion (21) is maintained in one of the operation positions. Furthermore, the over-center spring (5) allows the movement of the mobile portion (21) of the flap (2) to the emergency operation position when the mobile portion (21) receives an impact with a vertical force component exceeding a force threshold of the over-center spring (5).
