A device for temporarily loading, storing and unloading a container without deforming the container and affecting its contents. An enclosure (2) having struts (3) at both its left and right sides is provided. A support beam (4) of a transporter (10) that is provided with a pair of horizontal retaining fingers (13, 13) is attached in a vertically movable manner between the struts on the rear-surface side of the enclosure (2), and a plurality of horizontal shelves (20) is arranged between the struts on the rear-surface side of the enclosure with spaces (H) in a height direction of the container (19), the spaces being larger than the height dimension (h) of the container (19). Further, the retaining fingers (13, 13) of the transporter (10) are made to protrude toward the shelves (20) and the distance (L) between the pair of retaining fingers (13, 13) is made to be suitable for lifting the container.
