Abstract: A flap automatically-locking active air flap apparatus for a vehicle, includes a four-link mechanism that connects a driveshaft rotated by an actuator and a rotation shaft which separated from the driveshaft and about which the flap is rotated. Force of a traveling wind of a vehicle that rotates the flap and force of an actuator that locks the flap are set to be exerted in different directions when a four-link mechanism closes the flap. Thus, auto-locking is realized in a force equilibrium state. Accordingly, the flap is prevented from being open although the traveling wind of the vehicle applies a wind pressure to the flap. With a function of automatically locking the flap, the actuator producing a same output as an actuator in the related art is used without employing a separate structure, such as a stopper.
