Support 3 has a cylindrical shape with a bottom, and the upper end surface of support 3 (almost half
The surface 7a) of the spherical portion 7 is a spherical surface as in the first embodiment. Further, a restoration material 4 is provided on the inner peripheral side of the columnar portion 2. The restoration material 4 is formed by embedding a large number of core materials 6 inside a cylindrical body 5 formed of a flexible material such as rubber, and the restored restoration material 4 is placed in the hollow portion of the columnar portion 2. Before the support body 3 is fixed, the support body 3 is internally fitted and adhered and fixed to the inner surface of the columnar portion 2. The core material 6 is made of, for example, a steel cord used as a carcass cord material for tires, is oriented in the axial direction of the tubular body 5, and is arranged at substantially equal intervals in the circumferential direction of the tubular body 5. Has been done. When an impact is applied to the elastic post 1 configured as described above from the outside, the restoring material 4 bends together with the columnar portion 2 to absorb and absorb the impact, but along the upper end surface 3a of the support body 3 which is a spherical surface. Since the restoration material 4 bends smoothly, the restoration material 4 can be prevented from being damaged, and the durability of the restoration material 4 can be enhanced. When the external force is removed, the restoring material 4 restores the original shape favorably due to the restoring action of the core material 6. Further, even if an impact is locally applied to the elastic post 1, the columnar portion 2 and the restoration material 4 are dented inward to absorb and absorb the impact and restore favorably.
