Abstract
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.
