PURPOSE: A cleaner for a road sign using wind is provided to remove dust and pollutant from the surface of a road sign by periodically operating a cleaning system by storing kinetic energy in a battery. CONSTITUTION: A cleaner for a road sign using wind is as follows. A moving shaft(8) is attached to the side of a road sign(1). A generator(3) converts the rotating energy of a pinwheel(2) to electric energy. When energy has been sufficiently stored in a storage battery(4), the moving shaft moves a moving guide(6) with a motor(5) and removes pollutants, such as dust, using a brush(9).
