Fluid-filled vibration damping device

A fluid-filled vibration damping device, comprising:

• an inner member, an outer cylindrical member, and a main rubber elastic body, wherein the inner member and the outer cylindrical member are linked by the main rubber elastic body;
• a plurality of fluid chambers, provided inside the fluid-filled vibration damping device and filled with a magnetorheological fluid;
• an orifice path, allowing the fluid chambers to communicate with each other;
• and
• a magnetic unit, applying a magnetic field to the magnetorheological fluid in the orifice path and provided in an externally fitting state with respect to the outer cylindrical member,
• wherein the magnetic unit comprises:
• a magnetic field generation part that forms a magnetic field by being supplied with power;
• and a magnetic path formation part that induces a magnetic flux of the magnetic field formed by the magnetic field generation part,
• a magnetic gap part provided in the magnetic path formation part is disposed on an outer circumference of the orifice path, and the magnetic field is applied from the magnetic gap part to the magnetorheological fluid in the orifice path, and
• on an outer circumferential surface of the outer cylindrical member, an outer mounting member linking between the outer cylindrical member and a vibration damping linking target member is installed to an installation part, and the installation part is provided at a position offset from the magnetic field generation part in an axial direction,
• wherein the outer mounting member is an installation bracket linking the outer cylindrical member to the vibration damping linking target member, and
• the installation bracket installed to the outer cylindrical member penetrates through the magnetic path formation part.
