PROBLEM TO BE SOLVED: To provide a new traffic sign for giving a predetermined indication to a vehicle by being installed on a road.SOLUTION: A rod-like projection group 2 comprising a large number of projection units 1a is integrally erected on a top surface of a disk-like base 1. The heights of the respective projection units 1a are set to make respective upper ends of them wholly form an upward arc surface, by assuming such a form as to make the projection units close to a central portion of the disk-like base 1 highest and make the projection units gradually lower toward a peripheral edge. Furthermore, the upper ends are configured to be wholly formed of a material having flexible deformability based on an impact and restorability. |
