A fluid-filled type vibration damping device having a first and a second fluid chamber respectively filled with non-compressible fluid and which experience relative pressure fluctuations during vibration input, and provided with an orifice passage through which the first fluid chamber and the second fluid chamber communicate with one another, while being capable of exhibiting better dependability and durability in terms of effective vibration damping action of several types of vibration with different frequencies. In the device, tuning frequency of the orifice passage is varied by varying a passage length of the orifice passage 68 through adjustment of an insertion distance of an inside orifice member into an outside orifice member.
