To effectively prevent a merchandise from dropping undesirably owing to vibrations, etc., with a simple structure by setting the top plane of a device body as a front inclination plane of a prescribed angle that makes an upslope from its rear edge part to its front edge part.

The top plane 12 of a device body 11 is realized as an inclination plane forming an upslope from its rear edge part to its front edge part and its inclination angle θ is set to 5 to 15°, preferably to 10°. The plane 12 of the body 11 which makes such an inclination plane takes a part of inclining plural merchandises S which are heaped on the plane 12 and are stored in a merchandise column 2 backward by the angle θ and of shifting them to the back side of the column 2 (rear plate 21 side). As a result, plural merchandises S which are heaped in a backward inclination state and stored in the column 2, their rear end parts are controlled by the plate 21 and they are stored in a stair-shape with their front ends stuck out little by little.
