PROBLEM TO BE SOLVED: To solve the problem that there is dissatisfaction in safety when visibility is deteriorated, since an apparent width of a reflecting mirror becomes very narrower than an actual width, in a conventional curve mirror composed of a one-sheet reflecting mirror particularly installed in a gentle curve in a road.SOLUTION: For solving this problem, a first reflecting mirror and a second reflecting mirror are opposed so as to become nonparallel, and the first reflecting mirror is installed so that a crossing angle with a first road becomes 45 degrees or more and 90 degrees or less, and the second reflecting mirror is installed so that a crossing angle with a second road becomes 45 degrees or more and 90 degrees or less, and an image is reflected in two stages, and an apparent with of the reflecting mirror is expanded, so that safety is improved.SELECTED DRAWING: Figure 4
【課題】 道路において、特に緩やかなカーブに設置する、従来の1枚の反射鏡からなるカーブミラーでは、反射鏡の見かけの幅が実幅に比べて非常に狭くなり、視認性が悪化して安全性に不満があった。【解決手段】 この問題を解決するために、第１の反射鏡と第２の反射鏡を非平行になるように対向させ、第１の反射鏡は、第１道路との交差角が４５度以上９０度以下になるように設置し、第２の反射鏡は、第２道路との交差角が４５度以上９０度以下になるように設置し、映像を２段に反射させて、反射鏡の見かけの幅が広くなるようにして安全性を向上した。【選択図】図４
