Damping material vibration damping member using the damping material and seismic isolation apparatus incorporating the vibration damping member

摘要

The seismic isolation device 1 includes an annular laminated elastic body 6 in which thick steel plates 4 and 5, an elastic plate 2 and a thin steel plate 3 are alternately stacked, and an annular laminated elastic body 6 And a cylindrical plug 9 as a vibration damping material which is press-fitted into the inner periphery of the cylinder. The cylindrical plug 9 contains a thermally conductive filler such as a metal oxide, scaly graphite having an average particle size of 100 m or more, and a resin for imparting tackiness.
