Fluid-filled type vibration-damping device

A fluid-filled type vibration-damping device comprising:

• a main rubber elastic body of generally frustoconical shape;
• a first mounting member affixed to an axial upper end of the main rubber elastic body;
• a second mounting member affixed to an axial lower end of the main rubber elastic body;
• a pressure-receiving chamber formed axially below the main rubber elastic body, being partially defined by the main rubber elastic body and having a non-compressible fluid sealed therein;
• an equilibrium chamber having a non-compressible fluid sealed therein and formed between the main rubber elastic body and a flexible film by disposing the flexible film so as to cover an outside face of the main rubber elastic body;
• and
• an orifice passage through which the pressure-receiving chamber and the equilibrium chamber communicate with each other;
• wherein an equilibrium-chamber-side opening of the orifice passage is situated in proximity to an axial lower end of the outside face of the main rubber elastic body;
• wherein a guide groove extending in a straight line axially upward is formed on the outside face of the main rubber elastic body in proximity to the equilibrium-chamber-side opening of the orifice passage;
• and
• wherein a projecting rib that projects from the flexible film towards the guide groove is formed extending along the guide groove.
