Next, the operation of the lead-containing laminated rubber bearing 1 will be described with reference to FIG. The load of the upper structure 4 is transmitted to the lower structure 5 via the laminated rubber body 6. When the vibration force F is input to the lower structure 5 during an earthquake, the upper and lower structures 4, 5 are relatively displaced in the horizontal direction, and the laminated rubber body 6 undergoes elastic shear deformation. Due to its elastic characteristics, the input period is lengthened and transmitted to the upper structure 4 to perform seismic isolation. On the other hand, the lead plug 7 also undergoes plastic shear deformation along with the shear deformation of the laminated rubber main body 6, and absorbs vibration energy by the plastic deformation to perform a damping action.

Elongates in synchronism with the horizontal elongation of the laminated rubber body 6,
As a result, the coil spring 13 always surrounds the lead plug 7 over its entire length. That is, the lead plug 7 is always constrained by the coil spring 13, so that even if the laminated rubber bearing 1 is repeatedly subjected to shear deformation, the reinforcing plates 10, 11, 12
Of the lead plug 7 and the rubber layer of the lead plug 7 itself are prevented.

Further, during the shear deformation of the laminated rubber body 6, the coil spring 13 transmits the horizontal force caused by the horizontal movement of the intermediate reinforcing plate 12 to the lead plug 7 evenly in the longitudinal direction. Therefore, harmful deformation such as local deformation can be prevented from occurring in the lead plug 7. From the above, the laminated rubber bearing 1 exhibits the expected energy characteristics even if it is repeatedly subjected to a shearing action for a long period of time.
