PROBLEM TO BE SOLVED: To cover the side faces of a bed as a whole and to provide structure to be detached and folded so as not to occupy a wide space when it is not required. SOLUTION: A fence part 11 is almost equally divided into tree parts of 1st, 2nd and 3rd fence parts 13, 14 and 15 and mutually linked through hinge members 16 so as to be folded. Nuts are fitted and welded to the opened terminals of strut pipes 12a and 12d positioned outside among strut pipes 12a-12d, inserted into fence receiving pipes 19a and 19e of a side frame 18, fastened and fixed by thumbscrews 20, and resin caps are fitted to the opening terminals of the strut pipes 12b and 12c so as to be inserted and held into fence receiving pipes 19b and 19d. |
