Inactive gas enriched air, which contains higher concentration of inactive gas than concentration of inactive gas contained in air in the exterior space, is supplied to the holding space. A first opening for allowing containers being carried into and out of the storage structure to be moved through the side wall portion is formed in the side wall portion. A first inlet opening is located at a position in the exterior space and adjacent an edge of the first opening. A first drawing-in device is provided to discharge air drawn in through the first inlet opening into discharge space which is outside the holding space and is divided off from the exterior space.
