Abstract
A window covering includes a fixed rail, a covering material, a lifting cord and a winding mechanism, wherein the covering material is positioned under the fixed rail, and the winding mechanism includes a reel, a rotating member and a stopper. The reel is adapted to wind up or release the lifting cord, in order to drive the covering material to move toward the fixed rail to fold, or to move away from the fixed rail to unfold. The rotating member passes through the reel. The stopper is operably pivoted relative to the rotating member. When the rotating member rotates independently from the reel, the stopper is driven to pivot, and is protruded from a surface of the rotating member, and the stopper would abut against a block of the fixed rail to stop the rotation of the rotating member. Therefore, when a covering material of the window covering is unfolded and meets an obstacle, the covering material could stop unfolding automatically.
