[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Since ancient times, trees have been planted beside the roads to prevent snow and wind, forming snow and windbreak forests, and in recent years, mainly metal snow fences and windbreak nets have been installed to prevent damage.

[0003]

The problems described in the prior art have the following problems. A. Of course, it is aesthetically desirable to plant snow and windbreak trees, but even if you plant seedlings, it will take more than 10 years before they can be effective. In the case of expecting an immediate effect, it is necessary to plant a grown tree with a height of 3 to 4 m, but it will die soon if the geology and climate of the seedlings differ. In particular, there are few places with good geology along the road, and there are few examples of successful tree planting due to exhaust gas from automobiles.

B. When using a metal snow fence A method of attaching steel plates to steel columns, both of which are hot dip galvanized products that give road vehicles a feeling of closure. In the blow-off type, all the members have to be removed and stored when the season is off, which requires time and effort for removal and transportation, and requires a hangar. The blow-off type requires the following work when the season is off, and it takes the same work as the blow-off type. I. Roll up the snow plate and store it at the top. B. Hold the snow plate horizontally. C. Remove the snow plate and store it at the bottom. The blow-off type does the above work from the viewpoint of securing visibility and sunshine, but in any case, since the pillar is not removed, the road traveling vehicle still feels uncomfortable.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a device capable of solving the above problems.
