ABSTRACT:
A fluid-filled elastic mount including an elastic body for elastically connecting a first and a second support member, a partition structure cooperating the elastic body and a flexible diaphragm to partially define a pressure-receiving chamber and a variable-volume equilibrium chamber, respectively, which communicate with each other through an orifice, and a protective member fixed to the second support member for covering the diaphragm. The elastic mount has an elastic support member through which the protective member is elastically attached to the second support member and which cooperates with the protective member to provide a dynamic damper wherein the elastic support member is a spring member while said protective member is a mass member. This dynamic damper is effective to minimize resonating phenomenon of a mounting bracket used for fixing the second support member to one of two members that are flexibly connected by the elastic mount.
