PROBLEM TO BE SOLVED: To provide a seismic isolation support device which inhibits temperature rise of a damping body, in which vibration energy absorption capacity is deteriorated by the temperature rise, as much as possible even when being exposed to a long period earthquake motion and effectively achieves seismic isolation function even in the long period earthquake motion.SOLUTION: A seismic isolation support device 1 includes: a lamination body 5 having rigid layers 2 and annular elastic layers 3 which are alternately laminated; a cylindrical object 10 disposed in a hollow part 7 of the lamination body 5 and having a lead plug 9; and an outer periphery protection layer 12 covering an outer peripheral surface 11 of the lamination body 5.SELECTED DRAWING: Figure 1 |
