Abstract: A fluid-sealed engine mounting has a connector adapted to be connected to an engine, a base adapted to be connected to a vehicle frame, an elastic member joined between the connector and the base and elastically deformable in response to vibrations transmitted thereto, the connector, the base, and the elastic member jointly defining a fluid chamber in which a fluid is sealed, and a partition dividing the fluid chamber into a first chamber adjacent to the connector and a second chamber adjacent to the base, the partition having an orifice through which the first and second chambers communicate with each other. The engine mounting also includes a diaphragm mounted on the base or the connector for varying the volume of one of the first and second chambers when vibrations are transmitted to the engine mounting.

Abstract: A sub-frame supporting device in which a sub-frame adapted to support an engine, wheels and the like is supported from the body of a vehicle through an elastic support member. The supporting device comprises a pair of upper and lower holding plates oppositely disposed, a spacer pipe connecting the holding plates, a fastener for fastening the holding plates to a vehicle body and an elastic support member. A flange of the sub-frame is held between the elastic support member and a damper rib, and gaps are formed adjacent the upper and lower surfaces of the elastic support member. The rigidity of the elastic support member is set so as to be decreased with respect to vertical shearing force and increased with respect to lateral compressive force.
