Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a road sign pole capable of obtaining a stable fixing strength while reducing manufacturing and maintenance costs by forming a three-part assembly type, and reducing damage to improve entire durability.SOLUTION: A hollow pole body 1 bendingly deformable by contact or collision of other objects, a base 2 having a projecting portion 2A fittable into the lower end of the pole body 1 and a grounding annular portion 2B onto a road surface, and a ring 3 having an inner hole 3a externally fittable to the pole body 1 and an annular portion 3A facing the grounding annular portion 2B of the base, are manufactured as mutually independent components. The grounding annular portion 2B of the base 2 and the annular portion 3A of the ring 3 externally fitted to the pole body 1, are fastened and fixed to each other through bolts 4 from the lower side of the base 2. Thereby, the whole can be assembled in a state of holding and fixing a lower end annular portion 1c of the pole body 1 between both annular portions 2B, 3A.
