Abstract: As a vehicle drives into a curved road, the vehicle starts to move outwards due to a centrifugal force, which leads to the deceleration of the vehicle. If an apparatus of the present invention is installed on the vehicle, a repulsive force pushing the vehicle inwards is created due to a physical reaction principle in which a repulsive force pushing out the air flowing over the vehicle pushes an upper air progress plate outwards. Thus, the vehicle cannot receive a centrifugal force making the vehicle move outwards even on a curved road, so the overturning of the vehicle can be prevented, and also, even if the vehicle falls into a roadside reservoir, water can easily get into the vehicle through passages made on the rear side and the floor and holes through which the air crashing into the front side of the vehicle and becoming an obstacle in the progress flows into the inside of the vehicle, and therefore, a drowning accident caused when vehicle doors cannot be opened can be certainly prevented. Moreover, a lift force pushing the air on the front side of the vehicle can be reduced regularly, and even negative pressure drawing the air to be supplied to the rear side of the vehicle can be reduced, so a progress speed and fuel can be saved largely. Also, when the vehicle starts to drive on a straight road after passing the curved road, the vehicle does not need to be accelerated again, so the abrasion of a steel brake plate, a waste of important time and fuel consumption as well as fine dust can be reduced. We use vehicles to capitalize on their fast moving speed, and, for such reason, the vehicle does not need to be decelerated on the curved road, and can be driven still at its existing vehicle speed for the straight road without being accelerated again on the straight road, and such effect can save a large amount of fuel and time for acceleration.
