PURPOSE:To restrain raise of a spring constant in the axial direction in an intermediate and high frequency zone and so on by providing an elastic ring, where a rubber elastic body is molded between an outer cylinder and an inner ring, and a liquid seal elastic bush pressed in the inner circumference of this elastic ring. CONSTITUTION:In a liquid seal elastic bush 2, a metal inner cylinder 6 and an outer cylinder 7 are arranged in parallel to each other, and a sleeve-shaped rubber elastic body 8 is integrally molded between these cylinders 6 and 7. And an appropriate space is provided in the elastic body 8, and incompressive liquid is sealed in this space so as to form a liquid chamber 9. The two liquid chambers 9 which are divided by a central wall and separated by a transverse wall 12 are communicated with each other by an orifice 14 in the shape of a recess groove formed on the outer circumference and so on of a core metal 13. By this constitution, liquid in these both liquid chambers is moved in vibration, and damping characteristic is shown. |
