PROBLEM TO BE SOLVED: To provide a road sign body continuously usable because it easily returns to the original shape even if receiving external force.SOLUTION: The road sign body with a beam-like sign part erected between two columnar sign parts is constructed by erecting two inner posts with flexible pole parts projected upward on a construction surface, forming a locking part at the lower part outer surface of each inner post, forming each columnar sign part into cylindrical shape having a hollow part and opened downward, forming the lower part inner surface of each columnar sign part with an engaging part lockable to the locking part, enclosing the pole part of the inner post in the hollow part of each columnar sign part, and detachably locking the engaging part of each columnar sign part to the locking part of the inner post. Even if the road sign body receives external force and the columnar sign part bends, the deformed columnar sign part is supported from the inside by the pole part of the inner post in the hollow part and restored more powerfully. |
