Abstract

Official abstract text for this publication.

An anti-vibration device ( 1 ) includes a tubular first attachment member ( 10 ), a second attachment member ( 20 ), an elastic body ( 70 ), and a separating member ( 50 ) that separates a liquid chamber in the first attachment member into a main liquid chamber ( 80 ) and a secondary liquid chamber ( 90 ). A membrane is held by the separating member, and the membrane and a diaphragm are formed integrally.

First claim

Opening claim text (preview).

The invention claimed is: 1. An anti-vibration device comprising: a tubular first attachment member configured to be connected to one of a vibration generating portion and a vibration receiving portion; a second attachment member configured to be connected to another one of the vibration generating portion and the vibration receiving portion; an elastic body connecting the first attachment member and the second attachment member to each other; and a separating member separating a liquid-filled liquid chamber inside the first attachment member into a main liquid chamber and a secondary liquid chamber, the main liquid chamber being bounded by at least the elastic body and a membrane, and the secondary liquid chamber being bounded by at least a diaphragm, wherein the membrane is held by the separating member, the membrane and the diaphragm are formed integrally and the membrane is thicker than the diaphragm, the diaphragm is disposed further on an outer circumferential side than the membrane, the membrane has a surface on an opposite side of the main liquid chamber that contacts air and the diaphragm has surface on an opposite side of the secondary liquid chamber that contacts air, and the secondary liquid chamber is formed in an annular shape.
