<P>PROBLEM TO BE SOLVED: To provide a newly structured fluid-filled type vibration damping device which secures a durability of elastic partition wall of an elastic body rubber partitioning a plurality of pressure receiving chambers, and improves a vibration damping performance through increase of a fluid flow rate. <P>SOLUTION: A first mounting member 12 is positioned on one axial opening side of tubular portion 22 of a second mounting member 14, and a plurality of pockets 32a and 32b opening onto the other axial end surface are formed in the elastic body rubber 16. The openings of the pockets 32a and 32b are covered with a partition member 48 to form the plurality of pressure receiving chambers 58a and 58b. In the elastic partition wall 34 of the elastic body rubber 16 partitioning the plurality of pressure receiving chambers 58a and 58b, a dividing recess 70 opening onto the other axial end surface is formed. The opening of the dividing recess 70 is covered with the partition member 48, and thereby a dividing liquid chamber 74 filled with an incompressible fluid, is formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
