PURPOSE: A road sign board is provided to prevent damage to a sign board by separating the sign board from a magnet and rotating the separated sign board when a strong wind blows. CONSTITUTION: A road sign board comprises a post(100), top and bottom horizontal bars(200,300), a vertical bar(400), a cylindrical horizontal bar(500), a sign board(600), first and second magnets(700,800), fastening members(900), and a foundation structure(1000). The post is vertically installed on a road side. The top horizontal bar is connected to the top end of the post, and the bottom horizontal bar is connected to the middle end of the post to be parallel to the top horizontal bar. The vertical bar is vertically installed between the other sides of the top and bottom horizontal bars. The cylindrical horizontal bar is installed between the top and bottom horizontal bars through the vertical bar. The sign board is installed to be rotatable around the cylindrical horizontal bar. The first magnets are installed on the left and right bottom ends of the sign board. The second magnets are connected to the post and the first magnets and can be separated from the first magnets when a strong wind blows. The fastening members fasten the sign board to the cylindrical horizontal bar. The foundation structure fixes the post to the ground.
