Fluid-filled vibration damping device

A fluid-filled vibration damping device comprising:

• a primary liquid chamber;
• an auxiliary liquid chamber;
• a partition provided between the primary liquid chamber and the auxiliary liquid chamber;
• and
• a movable plate supported movably in a plate thickness direction thereof by the partition, the movable plate receiving on one face thereof liquid pressure of the primary liquid chamber and on another face thereof liquid pressure of the auxiliary liquid chamber so as to constitute a liquid pressure absorber, wherein
• at least one communication hole opens onto a surface of the partition, the surface facing the movable plate,
• at least one elastic protrusion projects from the movable plate toward the communication hole,
• the elastic protrusion includes a peripheral wall, the peripheral wall being configured to be pressed in a compression direction as well as in a shear direction and be elastically deformed to a radially inner side of the communication hole as well by means of the peripheral wall coming into contact with a wall portion of the communication hole due to movement of the movable plate in the plate thickness direction, and
• the elastic protrusion of the movable plate includes a hollow annular peripheral wall serving as the peripheral wall.
