To provide a stowage device having high stowage capability and a simple and compact structure and capable of simultaneously loading many kinds of products to stow different kinds of folding containers 12 having different height, respectively.

The folding container 12 is carried in in a carry-in part 22. A plurality of folding containers 12 are simultaneously stowed in a plurality of elevating means 61, respectively, in a transfer part 23. The plurality of elevating means 61 can ascend and descend independently, and an upper face position of the folding container 12 at the uppermost step is positioned at fixed stowage reference height per elevating means 61 to allow stowage of the folding container 12. A plurality of groups 13 of stage piling stowage articles stowed at a plurality of stages, respectively, by the plurality of elevating means 61 are simultaneously carried out by a carry-out means 25 to correspond to simultaneous loading of many kinds of articles for stowing different kinds of folding containers 12 having different height, respectively, although the structure of this stowage device having high stowage capability is simple and compact.
