A vibration damping device including: a main rubber elastic body connecting a first and a second mounting members; a fluid-filled unit having a tubular housing closed off by a rubber elastic wall and a flexible film for providing therein a fluid chamber filled with a non-compressible fluid, and a partition member positioned within the fluid chamber to form on a first side thereof a primary fluid chamber partly defined by the rubber elastic wall, and on the other side thereof a secondary fluid chamber partially defined by the flexible film, with these chambers communicating through an orifice passage; and a rigid piston member. Upon input of vibration across the first and second mounting members, pressure fluctuations is exerted on the primary fluid chamber through elastic deformation of the rubber elastic wall of the fluid-filled unit induced through pushing by the contacting member via the piston member.
