A rear engine mount includes a rectangular upper metal plate member, a metal stopper member, and a lower metal plate member. The metal stopper member includes a pair of side plates, and a bottom plate. The lower metal plate member is disposed a predetermined distance away from the upper metal plate member in a facing condition, with the metal stopper member disposed therebetween, and includes a pair of retaining portions provided at opposite end positions. A second stopper portion includes a pair of vertical plate portions standing on the lower metal plate member, and a horizontal plate member which is attached to the ends of the vertical plate portions and extended over the bottom plate of the metal stopper member. A pair of elastic rubber support members is bonded to the lower surface of the upper metal plate member at opposite end portions.

Vibration isolation mount

A fluid-filled vibration-damping device including an elastic body elastically connecting a first and a second mounting member to fluid-tightly close one open-end of the second mounting member, and mutually assembled a movable rubber plate bonded to a first support member and a flexible rubber layer bonded to a second support member are fluid-tightly fixed to the other open-end of the second mounting member by caulking such that the movable rubber plate cooperate with the elastic body to form a primary fluid chamber and the movable rubber plate and the flexible rubber layer cooperate to form an auxiliary fluid chamber, which are filled with a non-compressible fluid and connected together through an orifice passage. A partition member disposed in the auxiliary fluid chamber divides the auxiliary fluid chamber into an intermediate chamber partially defined by the movable rubber plate and an equilibrium chamber partially defined by the flexible rubber layer, which are connected together through a fluid passage, and includes an engaging piece extending toward and being engaged with the first or second support members to be provisionally fixed to the member upon assembly of the partition member. A method of producing the same is also disclosed.
