PROBLEM TO BE SOLVED: To remove the obstacle of the passage of a large-sized car, etc., and to prevent damage by installing at one corner of the intersection a strut having a horizontal arm extending to the central upper section of an intersection and having reflecting mirrors reflecting left and right roads hung down from front end sections thereof. SOLUTION: A horizontal arm 12 extending to a center is set up to a strut 11 installed at one corner of an intersection C. The strut 11 and the horizontal arm 12 are made of a steel pipe respectively. A plurality of connecting rods 12c are welded and connected to an upper material 12a and a stay member 12 respectively, thus constituting the horizontal arm 12. Reflecting mirrors 15 are installed at both end sections at the lower end of the vertical lever of a hanger detachably and slidably suspended from the upper material 12a, and two mutually orthogonal horizontal levers in a plane view are mounted. The reflecting mirrors 15 are inclined beforehand at an angle of 45 deg. so that the left and the right of roads crossing the fronts are reflected at the time of the viewing of the fronts in sections immediately before the intersection C respectively at every road R1-R4. Consequently, a space, in which an intersection mirror 10 is installed, can be economized. Accordingly, the obstacle of passage can be eliminated. |
