PROBLEM TO BE SOLVED: To provide a laminate structure of cushioning materials that can carry a heavy load, and has excellent impact-absorbing properties, impact resistance, and durability, and cushioning materials for heavy machines.SOLUTION: A polyurea resin layer is formed on the surface of a non-foamed rubber core body. A through hole for bolt fixing is also provided, and the polyurea resin layer is also formed on the internal surface of the through hole. The top face circumference of a body part that carries load has an arcuate peripheral cross section.SELECTED DRAWING: Figure 1 【課題】大きな荷重を支持することが可能であり、衝撃吸収性、耐衝撃性、耐久性に優れた緩衝材の積層構造及び重機用緩衝材を提供する。【解決手段】非発泡ゴム芯体の表面にポリウレア樹脂層を形成した。また、ボルト固定用の貫通孔を備え、該貫通孔の孔内の表面にもポリウレア樹脂層を形成した。荷重を支持する本体部の天面外周を断面円弧状とした。【選択図】 図１
