Engine mount

An engine mount (10) to be installed above an opening (4) of a vehicle body member (1) 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 (14), an upper fitting (12), a vibration-insulating base (16) of rubber elastomer interconnecting both fittings, a diaphragm (18) disposed within the main body fitting to face to the base, and a liquid-sealed chamber (20) partly enclosed by the diaphragm, the diaphragm being integrally provided at its lower circumferential end with a cylindrical rubber extension (34). 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.
