PURPOSE:To diminish adequately even high frequency vibrations by providing the boundary section between a liquid chamber and the outer side with an elastic membrane which is filled with cords for control of the quantities of deformation. CONSTITUTION:An internal liquid chamber 26 is divided into the upper liquid chamber 26A and the lower liquid chamber 26B by a cylindrical body 28 which has an orifice 32, and a rubber membrane 38 is set up in the boundary section between the upper liquid chamber 26A and the outer side. The rubber membrane 38 has a cord 40 built-in and stretched, which permits comparatively easy deformation of the rubber membrane 38 until it reaches the prescribed value of deformation, thus the deformation exceeding the prescribed value can be controlled. Therefore this rubber membrane 38 can adequately diminish even high frequency vibrations, making the damping of vibrations in a wide range. |
