PROBLEM TO BE SOLVED: To provide a vibration control device capable of providing stable vibration suppressing effects in a wide frequency range between a low frequency range and a high frequency range. SOLUTION: In this vibration control device A1, an annular liquid chamber 4 surrounding an inner tube member 1 is formed in a rubber elastic body 3 formed of a body rubber part 31 having a diaphragm inner tube 7 in which a body outer tube 6 and a diaphragm outer tube 2 are concentrically disposed on the outer side of the inner tube member 1 and which is fitted to one end part of the inner tube member 1 and installed between the inner tube member 1 and the body outer tube 6 and a diaphragm 32 formed of the diaphragm outer tube 2 and the diaphragm inner tube 7. The diaphragm 32 is adhered to only the outer peripheral surface 17 of the diaphragm inner tube 7 on the diaphragm inner tube 7 side. COPYRIGHT: (C)2005,JPO&NCIPI |
