For a load case of three-way open type, a side board 6 is swingably hinged to the before described edge frame 5 by a plurality of hinges 7. A rear door 10 is pivotally mounted to the upper part 12 of a fixed mast 11. While for a load case of one-way open type, a side board 13 is erectly secured to the edge frame 5 of quite the same bottom plate unit A, and the rear door is pivotally mounted to a rear top end part of the side board 13. |
