PROBLEM TO BE SOLVED: To provide a road marker which is easily adaptable to various kinds of height, and capable of firmly joining each component thereof without using any tightening means such as screws and rivets. SOLUTION: This road marker comprises a pole part 1, a cap part 2 and a base part 3. The pole part is a simple hollow columnar body, and the cap part is a common member, and the pole part is welded to the base part during the forming, and the road marker of various kinds of height can be formed only by changing the length of the pole part. In addition, a part of the base part is welded to an inner surface of the pole part and functions as a reinforcing member. Thus, no other reinforcing members need be provided separately, and a forming die of the base part can be simplified. |
