<P>PROBLEM TO BE SOLVED: To cause a position setting and mounting part formed by an upper surface of an upper plate of a lower case and inner surfaces of the right and left side plates and a position setting and fitting part formed by an outer surface of a connecting tongue piece at the bottom plate of the upper case and the bottom surface of the bottom plate to be fitted to each other when another case is stucked up above the former case, enable both cases to be stucked up under their position setting state through this mutual fitting and to prevent a slipping-off state of the upper case. <P>SOLUTION: Connecting tongue pieces 2a, 2a, 3a, 3a are formed at the right and left side edges of a bottom plate 2 and an upper plate 3 of a case member and at the same time the side plates 1, 1 of the case member are formed into plate-shape. The side plates of the case member are fixed under a state in which the upper side edges of the side plates protrude upwardly above the upper surface of the upper plate of the case member among the bottom plate and the right and left connecting tongue pieces of the upper plate and at the same time the lower side edges of the right and left side plates of the case member are embedded upwardly from the bottom surface of the bottom plate of the case member. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
