A front cross memberof a rear subframehas a recessed portionwhich is recessed continuously over a longitudinal direction thereof. The recessed portionis formed at a lower portion of the cross memberand is recessed upwardly, and an elastic bushis fitted in a resulting recess. The elastic bushhas an elastic elementwhich connects together an inner tubeand an outer tubewhich surrounds the inner tubeand is mounted on the rear subframeat the recessed portionas a bracket. The brackethas bracket plate portionswhich each have a plane which is brought into contact with an end face of the inner tube and folded-back portions. The bracketis disposed in such a manner as to hold therein both ends of the inner tubeand is configured such that the elastic bushis mounted thereon by passing a boltthrough the inner tube

A front subframeis formed of an aluminum alloy into a frame that is formed substantially into a shape of parallel crosses or into a rectangular shape and is made up of left and right front joint portionsand left and right rear joint portionswhich are disposed at corners of the frame that is formed substantially into the shape of parallel crosses or the rectangular shape, and left and right longitudinal membersand front and rear cross memberswhich connect the joint portionstogether. The left and right front joint portionsand the left and right rear joint portionsare formed of an aluminum alloy die-cast product, whereas the left and right longitudinal membersare formed of an aluminum alloy wrought product. In addition, connecting locations. . . of a camber angle adjusting mechanismare formed of an aluminum alloy die-cast product. Additionally, a rear cross member compoundis formed of an aluminum alloy die-cast product.

An engine mount system includes multiple liquid-filled engine mounts switchable to provide different mount characteristics by selectively introducing negative pressure or atmospheric pressure. On one of pipelines connected to the respective engine mounts for introducing the negative or atmospheric pressure into the respective engine mounts, a check valve and an orifice portion are provided in parallel. The orifice portion restricts an amount of air flowing therethrough, so that the mount characteristic of the engine mount connected to the one pipeline equipped with the check valve and the orifice portion does not undergo an abrupt change when the pressure introduced in the engine mount is switched from the negative pressure to the atmospheric pressure.
