In a gravestone structure including a foundation stone (2) and a headstone (3), four tip-resistant pads (4) and as many pressure plates (5) as the pads (4) are interposed between the foundation stone (2) and the headstone (3). Each of the tip-resistant pads (4) includes a sheet elastic body (6) and a point support member (7) embedded in an eccentric position in the sheet elastic body (6). The sheet elastic body (6) is formed of a transparent, flexible and elastic gel material that absorbs vibrations of the headstone (3). The point support member (7) is formed of a 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 the top surface of the foundation stone (2) with the point support members (7) oriented inward of the foundation stone (2).
