<p>PURPOSE:To increase the damping coefficient of a vibro-isolator dampen and reduce vibration and provide said vibro-isolator of simple constitution by an easy and unexpensive production method by contituting said vibro-isolator as that a supplementary wall in which a weight having the specified mass is resonated and operated with respect to input of vibration having a frequency near resonance frequency. CONSTITUTION:Of a cylindrical resilient wall 1 of rubber which has a single fluid chamber A therein and is to be the wall of the fluid chamber A, a part which constitutes the side wall of the fluid chamber A is formed as a main thick wall 11. Of the resilient wall 1 of rubber, a part which constitutes the bottom wall of the fluid chamber A is to be a sheet-like supplementary wall 12 having the specified expansive alastic modules. A weight 8 having the specified mass is embedded in the center part of the wall 12. The supplementary wall 12 responses to variation in internal pressure of the fluid chamber A and is vibrated at a higher frequency because the wall 12 has the specified mass and the specified expansive elastic modules. Vibration is thereby damped and reduced by quick increase in damping coefficient of the vibro-isolator.</p> |
