VIBRATION-DAMPING DEVICE

摘要

A thinned thickness portion 54 is formed to each of separating walls 42 that configure two second main liquid chambers 40 along an axis-orthogonal direction. The thinned thickness portions 54 extend from the thickness direction center of the separating walls 42 to the first main liquid chamber 28, such that the two sides of the thinned thickness portions are configured by thin walled portions 42U. The kinetic spring constants of the vibration isolation device are lowered in both the axial direction and the axis-orthogonal direction due to "pressure release" occurring.
