<P>PROBLEM TO BE SOLVED: To provide a dannage which has a stacking-up contacting wall for holding piled-up dannages at definite intervals and can be manufactured at a low cost, and to provide a vacuum-molding mold for the dannage. <P>SOLUTION: The dannage 10 has a structure wherein the stacking-up contacting wall 20 projects parts of a pair of side walls 12 and 12 opposing between adjoining hollow expanding parts 11 and 11 into hill shapes having ridge lines, respectively, extending upward and downward and welds mutual ridge line parts. Since the stacking-up contacting wall 20 is integrally molded with the dannage 10 like this, it is unnecessary to separately fit contacting components as a conventional one. In addition, since the stacking-up contacting wall 20 is composed of the hill-shaped projecting parts 21 and 21 having the ridge lines extending upward and downward, it does not form an undercut shape and a vacuum-molding mold for the dannage becomes inexpensive. It is possible thereby to manufacture the dannage 10 at a low cost. <P>COPYRIGHT: (C)2008,JPO&INPIT |
