A wind turbine includes a nacelle pivotally supported on top of a tower and having a tail rod, a rotator blade device mounted to the nacelle, a tail vane extended from the tail rod, two horizontal stabilizers mounted to the sides of the tail vane, a stable flap attached to the tail rod and located below one of the horizontal stabilizers, and a pivotal flap pivotally attached to the tail rod and located below the other horizontal stabilizer and pivotal relative to the tail vane to selectively engage with the horizontal stabilizer by a strong wind, and to generate a side force onto the tail vane, and to pivot the wind turbine and to deviate the wind turbine from a headwind and to prevent the wind turbine from being over-rotated or burned or damaged by the gale or strong wind.
