Abstract
A partition member having a rubber elastic membrane of a liquid filled vibration isolating device is provided. A ring-shaped metal fitting is formed by superimposing a first ring-shaped metal fitting on a second ring-shaped metal fitting. The first metal fitting and the second metal fitting are formed by press molding and are bonded integrally by means of the rubber elastic membrane thereby closing the opening of the ring-shaped metal fitting. Accordingly, the ring-shaped metal fitting of a complex configuration providing an orifice groove for forming the orifice is easily manufactured by simple working.
