2. Description of the Related Art For example, in the case of sign bodies, especially road sign bodies are provided on roads to provide traffic safety. However, since the sign bodies are constantly exposed to vehicle exhaust gas and dust, the sign bodies are immediately contaminated with the sign effect. However, there was a problem that the appearance was deteriorated or the appearance was impaired. Also, especially those installed in the tunnel,
Since it was not washed with rainwater or the like, the adhesion of soot in exhaust gas and mud scattered from vehicle tires and the like was remarkable. In addition, during snowfall, the marking effect was sometimes reduced due to the adhesion of snow.

Conventionally, in order to prevent such a decrease in the marking effect or the like due to dirt, a cleaning worker has to go to the installation location and wipe the dirt or snow with a cloth or a brush. Not only is a large number of cleaning workers required, but it is also time-consuming, and road markings used to separate two-way traffic lanes, such as inside tunnels,
Cleaning work was performed while regulating. In addition, there is a danger of a traffic accident, and thus the frequency of cleaning has to be reduced.
