To reduce the tensile distorsion generated in a rubber elastic body and improve durability.
This liquid enclosed type vibration control device is provided with a main spindle fixture 1, stopper member 2 including first and second rigid stoppers 22 and 23, intermediate cylindrical fixture 3 which comprises a pair of ring sections and first to third bridge sections 35 to 37 and wherein the third bridge section 37 is positioned in one side in the main vibration direction and which is arranged in the outer side of and concentric with the main spindle fixture 1, rubber elastic body 4 integrally connecting the main spindle fixture 1 and the intermediate cylindrical fixture 3, and external cylindrical fixture 5 which is arranged on the outside of and concentric with the intermediate cylindrical fixture 3 and formed with a main liquid chamber 53 and a sub liquid chamber 54 communicating each other through an orifice passage 55 between the first and second recessed sections 44 and 45 of the rubber elastic body 4, and in addition, is provided with a cavity section 47 which axially penetrating and is formed by the external peripheral face of the rubber elastic body 4 and the internal peripheral face of the intermediate cylindrical fixture 3 opposing to the external peripheral face of the rubber elastic body 4 in the side where the large tensile stress of the rubber elastic body 4 mainly works out of the main vibration input direction.
