To provide a laminated rubber bearing device with a hollow laminate advantageous in view of the prolongation of the quake-absorbing period, that is further improved so as to avoid the occurrence of buckling in the case of large deformation.
The laminated rubber bearing device includes the laminate 3 formed by alternately stacking a plurality of rubber layers 1 and rigid plates 2, a hole 6 formed at or near the central part of the laminate 3 so as to penetrate the laminate in the laminating direction, and a buckling-preventing columnar body 7 arranged in the hole 6. The buckling-preventing columnar body 7 is composed of a plurality of slide members 8 laminated in such a manner that they can slide laterally with respect to one another.
