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.
