VIBRATION DAMPING DEVICE

In a vibration damping device applying a magnetic force from a magnetic field generation unit to an orifice path communicating with fluid chambers into which a magnetic functional fluid is filled and controlling vibration damping properties. An intermediate cylindrical member to which an outer cylindrical member formed by a non-magnetic material is externally fit and fixed is formed by a ferromagnetic material. In the intermediate cylindrical member, a magnetic field acting opening part is provided at a position corresponding to the orifice path.
