Zusammenfassung:	PURPOSE: To obtain improved damping action in an enlarged vibration frequency range by designing the size of mutual damping openings in such a way as to cause the resonant motion of a liquid mass, and conforming them to the bulging elasticity of chambers. CONSTITUTION: A rubber body 14 includes two chamber bodies 13 comprising two chambers 1, 3 or 2, 4 overlapped in a damping direction D. The respective chamber pairs are spaced apart from one another by an elastic wall 15 and filled with operating liquid. Front walls 7-10 axially limiting the chambers 1-4 are different in bulging elasticity from one another. Individual bulging elasticity values are so determined that the bulging elasticity measurable on the whole are different from one another within a range of each chamber pair 13, thus obtaining improved damping action in an enlarged vibration frequency range.
