PROBLEM TO BE SOLVED: To exhibit movement regulation performance and cushioning performance of both an upper part and a side part by simultaneously restraining the upper part and the side part of an article, and to particularly exhibit upper or oblique upper movement regulation performance and cushioning performance even when strong impact to the upper side or the lower side of a packing object or external force in the rotation direction is applied.SOLUTION: A cushioning material is integrally constituted by having a top plate (1), a plurality of inside plates (2) bent outward from a peripheral part of the top plate, a plurality of extension plates (3) extended by bending from a tip of the respective inside plates, and a plurality of vertical plates (4) respectively extended as a vertical piece sideward and upward more than the peripheral part respective sides of a packing object by bending inward from the tip part or a side part of the respective inside plates or bending outward from the peripheral part respective sides of the top plate. The plurality of vertical plates (4) are extended in a plan view radial shape as a whole, and contact with at least any of an inside surface (102S) and a cover inner surface (102L) of a packing box (102), and thereby, regulate the movement in an upper space of the respective top plate, inside plate and side peripheral plate.SELECTED DRAWING: Figure 5 |
