Shock-absorbing structure and floor material

Abstract

The shock-absorbing structure includes a top plate including an upper surface to receive a load, and at least one leg extending in the Z-axis direction from the lower surface of the top plate and has a cross-sectional shape convexly flexed toward one side in the X-Y plane. When the load is applied from the upper surface side of the top plate in the shock-absorbing structure, the legs contract in the Z-axis direction to absorb the load until the load exceeds the threshold load, and once the load exceeds the threshold load, the legs become soft by bending toward the opposite side and being displaced largely while spreading their convexly-flexed cross-sectional surfaces in the Z-Y plane, and after the displacement, the legs can further absorb the load by abutting the upper side and the lower side of the side surface to contract in the Z-axis direction.
