PROBLEM TO BE SOLVED: To provide a signpost having a body column having high rigidity and hardly damaging.SOLUTION: The signpost comprises a base and a flexible body column of projecting upward from this base, this body column is provided with an outer column, an inner column and a reinforcement cylinder stored inside this outer column, the outer column and the inner column are arranged in a concentric circular shape and are undetachably provided on the base, and the reinforcement cylinder inserts a lower end cylinder wall between the inner column and the outer column and is provided in a state of not fixing to any of this inner column, the outer column and the base. Rigidity of the body column is enhanced by the reinforcement cylinder. Since the reinforcement cylinder is provided in a state of not fixing to any of the inner column, the outer column and the base, when the body column is broken and bent when a vehicle contacts with the outer column, an inner surface of the outer column and an outer surface of the reinforcement cylinder are slidingly positionally dislocated in response to deformation of the body column, and force concentration on a part of the reinforcement cylinder and the outer column is restrained, so that damage of the body column is reduced.
【課題】剛性が高く、損傷し難い本体柱を備える標識柱を提供する。【解決手段】ベースと、このベースから上方へ突出する可撓性を有する本体柱を備え、この本体柱に外柱と、この外柱の内側に収納される内柱及び補強筒を備えさせ、前記外柱及び前記内柱を同心円状に配置させて前記ベースに着脱不能に設け、前記補強筒は下端の筒壁を前記内柱と外柱との間に挿入させると共に、この内柱及び外柱及びベースのいずれにも固定させない状態で設ける。前記補強筒によって本体柱の剛性が高まる。また、前記内柱及び外柱及びベースのいずれにも固定されない状態で前記補強筒を設けるので、車両などが前記外柱に接触して本体柱が折れ曲がるときに、本体柱の変形にともない前記外柱の内面と補強筒の外面とが滑るように位置ずれし、補強筒や外柱の一部への力の集中が抑制され、本体柱の損傷が低減する。【選択図】 図２
