<P>PROBLEM TO BE SOLVED: To provide a fluid-filled vibration damping device with a novel structure capable of highly reliably obtaining vibration damping effect to vibration of a higher frequency than a tuning frequency of a first orifice passage. <P>SOLUTION: An elastic partitioning wall 62 is arranged in a main liquid chamber 58 side of a partitioning member 42, an air chamber 108 is formed between the elastic partitioning wall 62 and an opposing surface of the partitioning member 42, one end of a communication path 110 formed in the partitioning member 42 is a communication opening to the air chamber 108, the other end of the communication path 110 is an releasing opening 122 to the outer air, the releasing opening 122 of the communication path 110 is covered with a flexible lid 124. <P>COPYRIGHT: (C)2013,JPO&INPIT |
