Abstract
In a fluid-filled vibration damping device in which multiple fluid chambers filled with a magnetic functional fluid communicate with each other by an orifice path, and a magnetic unit applying a magnetic field to the orifice path is provided in a state of being externally fitting to an outer cylindrical member, the magnetic unit includes a magnetic field generation part forming a magnetic field and a magnetic path formation part inducing a magnetic flux, the magnetic field is applied from a magnetic gap part of the magnetic path formation part arranged on an outer circumference of the orifice path to 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 which is offset from the magnetic field generation part in an axial direction.
