PURPOSE: To expand the degree of freedom of a design for vibration isolating characteristics and also uniform rigidity in a shaft rectangular direction by embedding the first parts of a rigid member in both axial sides of a liquid chamber, and also arranging second parts for mutually connecting the first parts separately from the wall surface of an elastic body on the circumferential direction side of the liquid chamber to the center side of the liquid chamber. CONSTITUTION: Metallic inter rings 36 are embedded in an elastic body 18. The inter rings 36 have annular parts 36A as a pair of first parts and connecting parts 36B as a pair of second parts for connecting these annular parts 36A to each other, and consists of a metallic pipe, etc. When vibration is inputted to a vibration control device, the elastic body 18 is elastically deformed so as to absorb the vibration. In the vibration control device 10, a high rigid member is not embedded in the elastic body 18 composing the wall surface in the circumferential direction of a liquid chamber so that the liquid chamber is easily expanded/shrunk. Therefore, liquid can be resonated at low frequency, and the vibration having the low frequency in a direction for mutually connecting the liquid chambers can be effectively absorbed. |
