PURPOSE: To use a cushion body as a packing member in transportation of an quipment and as a vibration-proof material at the time of installing the equipment at a determined position by placing an equipment to be packed and an equipment to be installed at the determined position on the cushion body having the formation of a hollow part inside and a freely extensible and contractible bellows part on the outer peripheral part.

CONSTITUTION: The bellows parts 7 freely extensible and contractible in the height direction are formed on the side faces of the outer peripheral parts of the cushion bodies 6 and the hollow part is formed thereinside. When the equipment 2 is packed and transported, cushion bodies 6 are arranged on four corners under the equipment 2 to be packed and it is placed on these cushion bodies 6. Then, a vibration at the time of transporting is absorbed by the cushion bodies 6. When the equipment 2 after having been transported is installed in the determined position in an office, etc., the cushion bodies 6 are disposed on four corners under the equipment 2, then, it is placed and a caster 4 is separated from a floor surface. Thus, the vibration from the equipment 2 is absorbed by the cushion bodies 6.
