2. Description of the Related Art Conventionally, as a packing structure of this type, there is known a structure in which a cushioning material made of a polystyrene foam is interposed between an article such as an indoor air conditioner and a box covering the end. This Styrofoam molded product is made by conforming the shape of the inner surface to the outer shape of the end of the article, and the outer surface is attached to the inner surface of the box with an adhesive to cover the entire end of the article during transportation. Protects the article by absorbing external vibration such as.
However, due to the recent social demands for resource saving and waste saving, it is desired to shift to a simple packaging structure that eliminates plastic such as Styrofoam, especially in the air conditioning equipment industry.
Due to requests to reduce the amount of waste materials used at the installation site and to reduce unpacking and disposal time, it is urgently necessary to adopt a simple packaging structure consisting only of corrugated cardboard.

[0003]

However, corrugated paper cannot be molded as freely as Styrofoam molded products.
Since the cushioning ability is poor, it is difficult to obtain a good cushioning effect similar to that of the Styrofoam molded article without rattling, and there is no packaging structure capable of sufficiently absorbing impact with a simple structure having a small number of parts.

Therefore, an object of the present invention is to provide a shock-absorbing member having a simple structure using only corrugated cardboard and capable of sufficiently absorbing shock, and a packing structure and a packing using the shock-absorbing member for easy unpacking and disposal. To provide a method.

[0005]

In order to achieve the above object, the cushioning member of the present invention, as illustrated in FIG.
