ABSTRACT:
A laminated rubber bearing comprising a columnar-shaped viscoelastic body 5, a plurality of viscoelastic members 4, and an external binding body 1 disposed in the periphery of these components. The external binding body 1 is a laminated body consisting of alternating rigid plates 3 and rubber-like elastic plates 2 with rubber-like elastic plates 2 disposed between external peripheral regions of the rigid plates 3. The viscoelastic members 4 are disposed inside of those rubber-like elastic plates 2 of the external binding body 1 so that the viscoelastic members 4 fill up clearance between the rigid plates 3 inside of respective rubber-like elastic plates 2. A cylindrical cavity 6 open at both ends thereof extends through the viscoelastic members 4 and the rigid plates 3. A viscoelastic body 5, an elastic body, or viscous substance having cubage greater than that of the cylindrical cavity 6 is forcedly inserted in the cylindrical cavity 6.
