PROBLEM TO BE SOLVED: To provide a fluid-sealed vibration control connecting rod of an improved structure capable of preventing reduction in vibration control performance when a spring constant suddenly increases, with a tensile load made to act in the longitudinal direction of a rod body. SOLUTION: A main body rubber elastic body 100 has inner connecting rubber 104 and liquid chamber forming rubber 106 oppositely positioned in the rod longitudinal direction by sandwiching an inside slit 102, and a pressure receiving chamber 126 is formed in the liquid chamber firming rubber 106. A rod body 12 is formed with a balancing chamber 128 of constituting a part of a wall part out of a flexible film 60. Both these chambers 126 and 128 are communicated by an orifice passage 130. While, the inner connecting rubber 104 and the liquid chamber forming rubber 106 are allowed to abut on each other in the longitudinal direction of the rod body 12. COPYRIGHT: (C)2009,JPO&INPIT |
