PROBLEM TO BE SOLVED: To prevent the post from getting out of place in case of collision and increase the workability, by providing an air discharge and suction hole at the upper part and integrally forming a cylindrical post made of a flexible material and a support plate installed on the ground face. SOLUTION: A support rib is projected at the inner peripheral face of a post 10 and a retroreflecting sheet 15 is attached to time rugged face of the outer periphery of a groove formed at the upper part of the outer peripheral face. A number of discharge grooves 21 for compressed air are formed at the bottom face of the support plate 20 integrally formed at the lower part of the post 10. The post 10, the support plate 20, and the retroreflecting sheet 15 are coated with silicone in which a tin compound is diluted by silicone. The thickness of the fold of the connection part of the post 10 and the support plate 20 is made as thicker as about 10-50% than the upper thickness thereof. And hence, this delineator made of a flexible material prevents damage or reduce the damaged part of a vehicle to the minimum extent. In this way, this delineator prevents the post from getting out of place or separating in case of collision and the workability can be improved. |
