PROBLEM TO BE SOLVED: To make a low moving spring at a wide zone area in middle/high frequency areas. SOLUTION: The outer periphery part of an elastic member 3 formed integrally with the surrounding of an inner cylinder 2 is contacted closely in a non- combination to the inner surface of the outer cylinder 1. The partition wall 10 formed between the main liquid chamber 6 and sub-liquid chamber 7 communicated by an orifice passage 8 and the end wall of the axial direction both ends are adjusted so as to film resonate in the middle/high frequency area and the coupled resonance of the partition wall 10 and the end wall are set in the middle/high frequency area. A stopper 15 is projected integrally from the main liquid chamber cover 16 along the inner surface of the outer cylinder 1 in the main liquid chamber 6 and a liquid column is resonated between the partition wall 10 and end wall. The outer periphery surface of the inner cylinder 2 is a non- circular section and a resin made thick cover 42 is integrated on its surrounding.
