等の角で該交差道路の面に対して側面の軸方向が
略垂直になるように支持する支持部材とからなり
、 上記プリズムの側面を屈折率が大きくなるよう
に凹曲面としたことを特徴とする衝突防止器。[Claims for Utility Model Registration] Consisting of a polygonal prism and a support member that supports the prism at a corner of an intersection, such as in such a way that the axial direction of the side surface is substantially perpendicular to the plane of the intersection, A collision preventer characterized in that the side surface of the prism is formed into a concave curved surface so as to increase the refractive index.
