  The strut skin 1 is formed of a material having elasticity, for example, a polyurethane and ABS blend material having physical properties shown in Table 1 below so as to have a predetermined diameter and a predetermined length. It is not limited to this.

  The foam 2 is, for example, a semi-rigid foamed polyurethane having the physical properties shown in Table 2 below, but the material is not limited to this semi-rigid polyurethane.

  The pedestal 3 is, for example, polyurethane having the physical properties shown in Table 3 below, but the material is not limited to this polyurethane.

  The cap 4 is, for example, polyethylene having the physical properties shown in Table 4 below, but the material is not limited to this polyethylene.

  The reinforcing body 7 is formed into a cylindrical shape from a material having a desired reinforcing characteristic, for example, a resin having the same physical properties as a metal plate or a column outer shell, but the material and shape thereof are not limited thereto. It is not something.

  The vehicle stopper according to the present invention is made of the material as described above, and has an embedded leg (not shown) embedded in the ground at the lower end of the support outer shell 1 and a hooked bolt 6 screwed downward. The protruding pedestal 3 and the reinforcing body 7 are formed integrally, and separately, the foam 2 is injected into the outer shell 1 and foamed and cured. In the case of this embodiment, the cap 4 was put on the top of the column outer shell before the foam was injected and integrated with the column outer shell and the foam during the filling molding of the foam 2. The method can be arbitrarily performed, such as fixing with an adhesive, fixing with a rivet, and fixing with an adhesive and a rivet. In this embodiment, an example is shown in which a cap molded by a blow molding method is used. However, the cap can also be manufactured by a casting molding method or an injection molding method. Regarding the material, polyethylene is used in this embodiment, but resins such as polyurethane, EVA, and polypropyne can be used.
