Abstract

An anti-vibration structure 10 includes an inner elastic body that is a separate body to a multi-layered material and that is disposed in a through-hole piercing through a layering direction of the multi-layered material, and a restricting member that has at least a portion embedded in the inner elastic body, that has one end coupled to an upper plate and another end coupled a lower plate and that restricts separation of the upper plate and the lower plate.

First claim

1 . An anti-vibration structure comprising:
a multi-layered material in which a plurality of rigid hard plates and a plurality of soft plates with viscoelastic properties are layered alternately to each other; an upper plate and a lower plate that are respectively layered at each layering direction side of the multi-layered material; an inner elastic body that is a separate body from the multi-layered material and that is disposed in a through-hole piercing through the multi-layered material in the layering direction; and a restricting member that has at least a portion embedded in the inner elastic body, that has one end coupled to the upper plate and another end coupled to the lower plate, and that restricts separation of the upper plate and the lower plate.

2 . The anti-vibration structure of claim 1 , wherein the multi-layered material is pre-compressed by the restricting member.

3 . The anti-vibration structure of claim 1 , wherein the inner elastic body is pre-compressed by the restricting member.

4 . The anti-vibration structure of claim 2 , wherein an outer circumferential face of the inner elastic body and an inner circumferential face of the multi-layered material abut each other without a gap due to the pre-compression.

5 . The anti-vibration structure of claim 1 , wherein at least one of the through-hole or the inner elastic body has a tapered shape in which one end side in the layering direction has a smaller diameter.
