To enhance a tip resistance effect for a heavy article by increasing an effective area of a sheet elastic body exhibiting a vibration absorbing function.

In a gravestone structure 1, four tip-resistant pads 4 and as many pressure plates 5 as the pads 4 are interposed between a foundation stone 2 and a headstone 3. Each tip-resistant pad 4 has a point support member 7 embedded in an eccentric position in a sheet elastic body 6. The sheet elastic body 6 is formed of a flexible and transparent gel elastic material that absorbs vibrations of the headstone 3. The point support member 7 is formed of metal or resin harder than the gel elastic material and undergoes plastic deformation under the load of the headstone 3. In order to render the gravestone structure 1 seismically isolated, four tip-resistant pads 4 are arranged on a top face of the foundation stone 2 with the point support members 7 oriented inward of the foundation stone 2.
