PURPOSE: An automatic no-parking signboard provides convenience to a user by manufacturing a signboard which can be automatically moved. CONSTITUTION: An automatic no-parking signboard comprises a sign part, an elastic bar, an air hole, a support, a circular groove, and a screw type connection. The elastic bar is formed to be bent and stood. The air hole allows air of a sign part to be got out. The support supports the weight of a vehicle, and reduces the angle that the elastic bar is bent and the area touched with wheels of the vehicle. The circular groove is inclined so that the elastic bar is not bent more than 50°. The screw type connection is coupled to a fixing plate composed of a screw type connection insert.
