Description

The elastic body restraint degree variable structure according to the present invention is used as a support device for supporting various structures such as buildings and bridges, and includes a first rigid body, a second rigid body, and the first rigid body. An elastic body disposed between the elastic body and the second rigid body, and an elastic deformation restraining body that surrounds the elastic body at a position where the elastic body that is elastically deformed approaches or contacts. In a state where a predetermined value or more is input, the elastic body has a convex portion and / or a concave portion on a side surface, and the elastic deformation restraining body is brought into contact with and / or pressed against the deformed elastic body. Constrain deformation. That is, when an input exceeding a predetermined value is made, the elastic body is elastically deformed so as to reduce the volume of the gap created by the convex portion and the concave portion, and the deformed elastic body hits the restraining body. The deformation of the elastic body is constrained by contact and / or pressure contact. For example, the elastic body is surrounded by the first rigid body, the second rigid body, and the elastic deformation restraining body to be in a substantially sealed state, and the higher the load on the elastic body, the more advanced the elastic body. It changes to a sealed state. In such an elastic body restraint variable structure, when a load is input, the elastic body deforms so as to fill the gap formed by the concave portions between the convex portions according to the magnitude of the input, The degree to which the portion comes into pressure contact with the restraining surface of the elastic deformation restraining body increases. The elastic deformation restraining body restrains such deformation of the elastic body.
