Vibration preventing rubber mount

Abstract

Abstract PURPOSE:To provide an effective vibration preventing effect in high and low frequency regions by affording communication between an inside pocket portion and an outside pocket portion provided circumferentially in two rows within a rubber elastic body. CONSTITUTION:A rubber block 2 is transformed by an axial load to contract an inside pocket 12 and flow non-compressive fluid therein into a recess 34. On the other hand, since an outside pocket portion 14 has a thin peripheral wall 16, it is expanded by the outflow pressure, and the non-compressive fluid flows through the recess 34 so that vibration in low frequency region is alleviated effectively by the flow resistance. Even when pinch displacement is added, the non-compressive fluid pushed out by the transformation of the inside pocket portion 12 is flowed into the outside pocket portion 14 by the transformation of the rubber block 2, so that the vibration is effectively alleviated.
