PROBLEM TO BE SOLVED: To provide a sign post having excellent restorability after the pole has been deformed, and which can maintain an erected state for a long time.SOLUTION: A flexible pole is provided with: a cylindrical outer column; a cylindrical first inner column stored inside thereof; and a cylindrical second inner column arranged on the farther inside and stored in the outer column. The inner diameter of the first inner column, which is undetachably provided on a base, is formed to be 1.5 mm or greater than the outer diameter of the second inner column. When the outer column is deformed, the first inner column and the second inner column support the outer column inside thereof, allowing recovery from the deformation; thus, the erected state of the outer column can be well maintained. As the inner diameter of the first inner column is formed to be 1.5 mm or greater then the outer diameter of the second inner column, damage to the columns can be reduced by suppressing the friction between the inner peripheral surface of the first inner column and the outer peripheral surface of the second inner column when the first inner column and the second inner column are deformed so as to be bent by the external force received by the outer column.SELECTED DRAWING: Figure 4
【課題】ポールが変形した後の復元性が良好であると共に、立設状態を長く維持できる標識柱を提供する。【解決手段】可撓性を有するポールに円筒状の外柱と、その内側に収納させる円筒状の第一の内柱と、更にその内側に配置させて前記外柱に収納される円筒状の第二の内柱とを設け、前記ベースへ着脱不能に設けた前記第一の内柱の内径を前記第二の内柱の外径よりも１．５ｍｍ以上大きく形成させる。前記外柱が変形した場合に、その内側で前記第一の内柱と共に第二の内柱が前記外柱を支えて変形を復元させ、外柱の立設状態を良好に継続できる。前記第一の内柱の内径を前記第二の内柱の外径よりも１．５ｍｍ以上大きく形成するので、前記外柱が受けた外力によって前記第一の内柱と第二の内柱とが曲がるように変形したときに、第一の内柱の内周面と第二の内柱の外周面との間の摩擦が抑制され、これらの損傷を低減できる。【選択図】 図４
