PURPOSE:To provide a cushioning device excellent in cushioning function and easy to dispose by a method wherein a plurality of cylindrical bodies are retained by a connector with their peripheral surfaces disposed in adjacent relation and are arranged at such a space as to bring the adjacent peripheral surfaces into contact with one another by the compressing and deformation. CONSTITUTION:A cushioning device 1 has a plurality of cylindrical bodies 3 arranged at suitable spaces between two sheet members 2 serving as a connector and fixed to the sheet members with adhesive agent. The cushioning device 1 can obtain the stress resulting from the deformation of each paper pipe occurring in its own way due to the compression of each cylindrical body 3. By further compression, the side parts of adjacent cylindrical bodies 3 make contact with one another, so that the contact area at the side parts thereof will become large. During this process, the stress increases describing a secondary curved line. For this reason, the cushioning device is so designed as to apply the load before buckling to the vertical contact part between the compressed and deformed cylindrical bodies 3, whereby the stress a few times that caused by the deformation of each cylindrical body 3 occurring in its own way by compression, together with a sufficient restoring function, is obtained. |
