摘要

A seismic isolation support for bridges 1 has, in addition to a rubber plate 2 and a steel plate 3, a laminated body 7, a hollow space 8 provided by being sealed inside the laminated body 7, and a lead plug 9 that densely fills the hollow space 8. The lead plug 9 has a pair of rectangular faces 71 in the direction C perpendicular to the bridge axis direction that face each other in the bridge axis direction B, and a pair of rectangular faces 72 in the bridge axis direction B that face each other in the direction C perpendicular to the bridge axis direction.
