。[Claims for Utility Model Registration] (1) An elastic body is interposed between the mounting member attached to the vibrating body and the mounting member attached to the support body, and a partition member is provided on one of the mounting members,
A generally conical main fluid chamber filled with a fluid whose diameter expands on the partition member side is defined between the partition member and the elastic body, and the main fluid chamber is filled with a fluid separated from the main fluid chamber by the partition member. The secondary fluid chamber is expandably and contractably defined, and a damping passage is formed that opens on the outer circumferential side of the partition member to communicate the main fluid chamber and the secondary fluid chamber. In a fluid-filled vibration isolator, a fluid-filled vibration isolator is provided with a regulating part protruding from the elastic body or the mounting member, which abuts the mounting member or the elastic body to define the maximum displacement of the elastic body when the elastic body is excessively deformed, A fluid-filled vibration damping device, characterized in that a flow path is formed which communicates the damping passage inwardly from the regulating portion of the main fluid chamber in a state where the damping passage is in contact with the regulating portion. (2) An elastic body is interposed between the mounting member attached to the vibrating body and the mounting member attached to the support body, and a partition member is provided on one of the mounting members,
