Description of the Related Art A pillar of a conventional general house is generally received on a horizontal base (material), and the base is directly attached to the base (material) via a packing plate made of synthetic resin. ) Fixed. Thus, the only play between the base and the foundation is the elastic deformation of the packing plate. Therefore, in the event of an earthquake, vertical vibrations (vertical load) and horizontal vibrations (horizontal load) are almost not absorbed by the packing plates and are transmitted from the foundation to the support pillars through the foundation as it is, which may cause serious damage to the house. . Especially in the case of a direct earthquake, a large instantaneous vertical load due to a thrust from the underground is directly transmitted to the pillars, resulting in a large impact on the entire house.
