PROBLEM TO BE SOLVED: To facilitate the recognition by a driver by providing a colored exterior body covering the surface of a reflector formed into the irregular surface by diamond cutting and dividedly or integrally molded into a cylindrical shape or an elliptic shape to form a wide-angle reflector. SOLUTION: The surface 2a of a reflector 2 is formed into irregularities 2c such as diamond cut, triangular pyramids, of square pyramids so that the light is reflected in all directions, and the back face 2b is mirror-machined by silver plating. The irregularities 2c may be formed on the back face 2b or on both faces. An exterior body 3 is made of a transparent body, and it is held to cover the reflector 2. One or both of the exterior body 3 and reflector 2 are colored in yellow or orange. A supporter 4 supports the reflector 2 and exterior body 3 and is communicated with a stanchion 5. The reflector 2 may be formed into an elliptic shape or a cross shape other than a cylindrical shape, or it may be dividedly or integrally molded. A driver can judge the curved state of a road and can safely drive a vehicle. |
