The invention discloses a wind-resistant advertising board comprising a frame and a main board. The main board is composed of a plurality of blades arranged side by side. The blades are hinged to the frame. The frame is provided with a steering driving assembly for inducing wind power to drive the blades to rotate. The steering driving assembly comprises a plurality of gears, racks and a sliding block. The gears are fixed to the plurality of blades. The sliding block extends and has a first windward piece. A windward surface of the first windward piece is parallel to the main board. The sliding block is driven by wind to slide in a direction vertical to the arrangement direction of the blades. The racks are intermeshed with the plurality of gears. The racks are hinged to the sliding block via draw bars. When the sliding block is moving in a first sliding chute back and forth, the sliding block drives the racks to move in the arrangement direction of the blades. The first sliding chute is provided with elastic components to keep the sliding block to reset. The advertising board can be normally used under the normal or breeze condition and is capable of dispelling wind when subject to large head-on wind, and wind resistance of the advertising board is improved.
