PROBLEM TO BE SOLVED: To provide a laminated rubber load device allowing the continuation of a specified test by preventing a sudden lowering of load even if setting occurs to a rubber layer when making the test by applying vertical load to laminated rubber. SOLUTION: Disc spring type pressure accumulating structure 40 elastically displaceable by interposing a disc spring means 43 between an upper receiving member 41 and a lower receiving member 42 is disposed in a stacked state on a laminated rubber support body. The pressure accumulating structure and the laminated rubber support body in the stacked state are pressurized by a jack or the like and compression-displaced by a specified quantity. The pressure is then released to hold the compression-displaced height as it is. |
