A fluid-filled vibration damping device includes a switching valve arranged inside the fluid passage passing through a partition member to communicate with a main fluid chamber and a sub fluid chamber and protruding from one wall surface toward the other wall surface of the fluid passage that face each other. A gap is provided between the switching valve and the other wall surface. A tip end part of the switching valve abuts against the other wall surface through a tilt displacement in a swing manner of the switching valve in the passage length direction of the fluid passage to thereby form a switching mechanism for closing the gap. An elastically deformable fin-shaped protrusion protruding from the tip end part of the switching valve toward the other wall surface is provided. A leak passage is formed between a protruding tip end of the fin-shaped protrusion and the other wall surface.
