A liquid-filled engine mount is disclosed which includes a rubbery elastic member interposed between an engine and a vehicle body, a diaphragm positioned in opposed relation to the rubbery elastic member. The engine mount defines a liquid chamber therein. The liquid chamber holds an actuating liquid therein. The liquid chamber has a partition wall disposed therein. The partition wall separates the liquid chamber into primary and secondary chambers. The primary chamber is provided on a side of the elastic member while the secondary chamber is provided on a side of the diaphragm. The partition wall has first and second orifices extending therethrough. The first orifice communicates with both the primary chamber and the secondary chamber. The second orifice communicates with the primary chamber. The first and second orifices provide different resistances to the liquid flowing therethrough. The engine mount includes a resilient means for urging the diaphragm against the partition wall to close an opening of the second orifice. The engine mount includes a diaphragm driving means for forcing the diaphragm against a resilient force the resilient means exerts on the diaphragm to thereby open the opening of the second orifice, such that the second orifice communicates with the secondary chamber. The diaphragm has plural projections formed on a surface thereof.

A fuel tank is supported by an upper surface of a subframe, inclined surfaces abutting four corners of the fuel tank, and steel straps passed across the upper surface of the fuel tank. Thus, the fuel tank can be securely mounted on the subframe without involving any play, and it can be accomplished by engaging relatively rigid and mechanically strong parts of the fuel tank. Thus, various advantages obtained by mounting a fuel tank on a subframe can be obtained without any need to reinforce the fuel tank or the subframe or to take any costly special measures.

In an automotive subframe having a rectangular annular shape as seen in plan view, the longitudinal members have closed cross sections, but the lateral members open cross sections and are provided with open parts adapted to receive a flange projecting from the fuel tank. Because the lateral members have open cross sections, the subframe is capable of undergoing a twisting deformation relatively easily, and the sloshing movement of the fuel inside the fuel tank would not be directly transmitted to the vehicle body. Because the longitudinal members have closed cross sections, and therefore have a relatively high rigidity, the wheel suspension system can be securely supported without creating any possibility of changes in the wheel alignment. Furthermore, the open part of the lateral subframe member can conveniently receive the flange of the fuel tank, and it is possible to maximize the capacity of the fuel tank without causing any interference between the fuel tank and the lateral member.
