PROBLEM TO BE SOLVED: To form a supporting surface for a body to be housed by connecting respective cylindrical bodies, and provide a cushioning body which can be transported under a sheet state, and of which the disposability after usage is high by engaging a U-shaped frame body with insertion grooves which are provided on both end sides of a supporting body comprising a plurality of cylindrical bodies having different heights. SOLUTION: From both sides of one pair of edges of a bottom plate surface, a blank sheet where a side surface plate 6, an upper surface plate 7 and an internal contact plate 8 are provided, is built up, and a supporting body 3 is formed by connecting two cylindrical bodies having different heights. In the meantime, a frame body 4 is formed by bending a blank sheet, which is constituted of an external plate, a width plate and an internal side plate 12, into a U-shape. In this case, an insertion groove is provided on both end sides of the upper surface plate 7 of each cylindrical body 2, and by inserting an insertion piece which is formed on the internal side plate 12 of the frame body 4 in the insertion groove, both parts are engaged. Thus, a supporting surface for a body to be housed is formed of the upper surface plate 7 of the lower cylindrical body 2 of the supporting body 3, the internal contact plate 8 of the higher cylindrical body 2, and the internal side plate 12 of the frame body 4. |
