FLUID-SEALED ACTIVE VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fluid-sealed active vibration control device with a new structure which makes excellent both mounting workability and mounting strength with respect to a second mounting member of a rubber stopper, which has a simple structure of a small number of components. SOLUTION: In a fluid-sealed active vibration control device 10, a locking hole 166 and engaging hole 168 are formed in an abutting part 52 which is a mounting object of a shock absorbing rubber 150 while a locking protrusion 158 and engaging protrusion 160 are integrally formed with a shock absorbing rubber 150 constituting a stopper mechanism 148 (a). A locking mechanism 170 for preventing the locking protrusion 158 from being pulled out of the locking hole 166 is constituted by engaging the engaging protrusion 162 projecting above the outer peripheral surface in a tip of the locking protrusion 158 with the peripheral edge of the locking hole 166 (b). A holding mechanism 172 for keeping the engaging protrusion 162 and the peripheral edge of the locking hole 166 in the engagement state is formed by inserting the engaging protrusion 160 into the engaging hole 168 to prevent the rotation of the locking protrusion 158 (c).
