PURPOSE: To prevent articles stored from falling from forward, by a method wherein a storing case is set-up by only stacking a number of case members vertically and by only fitting fit parts to other fit parts just below the fit parts, and the articles to be stored is stored on each top board inclined front-up.

CONSTITUTION: Each of fit parts A is so formed that at the upper part thereof, a groove 4a opening to the outside is recessed in horizontal direction not parallel to the incline of a top board 3 and that at the lower part of the groove 4a, a projection line 46 facing to the inside is protruded almost parallel with the groove 4a. The projection line 4b on the fit part 4 of a case member 2 at the upper tier is slidably fitted into the groove 4a of the fit part 4 of another case member 2 at the lower tier. In this way, any number of the case members 2, each of which is in the same form and is opened to a front side A and to a down side C, can be vertically stacked, and a storing case 1 having a required number of storing spaces 7 can be set-up at will. Since the fit parts 4 are vertically formed downward at both sides of the top board 3, the top of the top board 3 is made flat, and since the top board 3 is inclined front-up, stored articles can be prevented from falling from at the front side A without forming a rib or the like at all, and can be easily taken out. Furthermore, the top of the case member 2 in the highest position can be also utilized.
