PROBLEM TO BE SOLVED: To provide a road marker requiring little trouble or cost for adding various functions or forming it in various shapes. SOLUTION: The road marker comprises a pole part, a cap part and a base part, which can be separated from each other. The pole part is a simple hollow cylindrical body. Accordingly, only by forming inserting parts with the same outer diameter as the inner diameter of the pole part in the cap part and the base part, shapes of other parts than the inserting parts can be changed and other members can be added, so that the road marker can have various shapes and functions. Moreover, road markers with various heights can be formed only by changing the length of the pole part. |
