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

Abstract: An engine mount having a vibration isolating base body formed of a rubber elastic body interposed between a body side metal fitting and an engine side metal fitting. A stopper mechanism which absorbs an excessive displacement of an engine mount is provided. The stopper mechanism is constituted of a cylindrical metal fitting provided at said body side metal fitting and a stopper rubber portion provided at said engine side metal fitting opposed to the cylindrical metal fitting. Said stopper rubber portion is constituted of an outer peripheral flange protruding radially outwardly from the engine side metal fitting, a coating rubber layer covering said outer peripheral flange and a reinforcing metal fitting of a L-shape cross section embedded in said coating rubber layer.

Abstract: An engine mount has a stopper rubber portion constituted of an outer peripheral flange protruding radially outwardly from the engine side metal fitting and a coating rubber covering an outer periphery of said outer peripheral flange. A radius of curvature of contact parts positioned at one direction of two radial directions orthogonal to each other in a radial plane substantially equals to a radius of curvature of an inner periphery of the body side metal fitting and a thickness of the coating rubber positioned in said one direction is constant in a circumferential direction thereof, whereby the contact parts positioned in said one direction are widely brought into contact with the inner periphery of the body side metal fitting and distorted uniformly. The distortion of the stopper rubber portion is also made uniform when applying a load thereto.

Abstract: An engine mount to be installed above an opening of a vehicle body member to support the engine in vibration-proof fashion, on which the intrusion of foreign matter from the opening can be precluded without increase in components. It comprises a cylindrical main body fitting, an upper fitting, a vibration-insulating base of rubber elastomer interconnecting both fittings, a diaphragm disposed within the main body fitting to face to the base, and a liquid-sealed chamber partly enclosed by the diaphragm, the diaphragm being integrally provided at its lower circumferential end with a cylindrical rubber extension. The rubber extension extends downwardly from the diaphragm, lower edge thereof being turned-up to come in contact with a peripheral edge portion around the opening thereby to close the opening.
