Abstract
A fluid-filled vibration damping device wherein a partition member is formed by fitting an inner orifice member inside an outer orifice member with the members relatively displaceable. An orifice-defining window is provided on either one of an inside peripheral face of the outer orifice member and an outside peripheral face of the inner orifice member. An orifice passage is defined utilizing a zone being produced through partial covering of the orifice-defining window by the other of the outer orifice member and the inner orifice member. The covered zone of the orifice-defining window changes through relative displacement of the inner orifice member and the outer orifice member, so that a passage length along the orifice passage changes in association with change of the covered zone of the orifice-defining window.
