  FIG. 10 is a cross-sectional view showing the coupling structure between the pedestal and the sign post body of Patent Document 1;

  The marker column body a is a hollow cylindrical body formed of a material having required physical properties such as polyurethane, and a flange portion a1 extending in the horizontal direction at a lower end thereof and a hanging portion bent downward from a peripheral edge of the flange portion a1. Part a2 is formed. The pedestal b is a formed product made of polyethylene or the like, and has an upper and lower pedestal b1 and a lower pedestal b2, and is divided into upper and lower parts. Although not shown, the upper pedestal b1 is further divided into three parts. It has become. The upper pedestal b1 and the lower pedestal b2 are formed with a vertical pinching part b3 and a horizontal pinching part b4 corresponding to the flange part a1 and the hanging part a2 of the marker column main body a, The flange portion a1 of the sign post body a is sandwiched by the vertically sandwiched portion b3, and the hanging portion a2 of the sign post body a is sandwiched by the left and right sandwich portion b4, and the fixing screw C is tightened in this state. The upper pedestal b1, the lower pedestal b2, and the sign post body a can be firmly fixed.

  Since the prior art shown in FIG. 10 is configured as described above, when the sign post body or a part of the upper and lower pedestals are damaged due to contact with the vehicle, etc., only the damaged parts need to be replaced. Maintenance costs can be reduced. However, this conventional technique has a problem that the manufacturing cost is increased because the molded article having the flange portion and the hanging portion must be used as the sign post body. A pinching structure is adopted for the purpose of withstanding a collision at a time (about 20 KM / H), so when sudden braking is applied on a signpost at a higher speed (for example, 30 KM / H or more). May cause the sign post body to detach from the pedestal and scatter.
