PROBLEM TO BE SOLVED: To provide a new base structure of a receptacle for a shelf board where insertion of a sliding member and positional change of the shelf board are performed easily and speedily. SOLUTION: The structure consists of a pair of wall surface members 2 and the sliding member 3. Each of the wall surface members 2 consists of a columnar body which is vertically long, which has a groove 4 formed in the longitudinal direction, and which has engaging parts 5 at a plurality of places for engaging the sliding member 3 within the groove. The sliding member 3 is provided so as to be slidable within the grooves of the wall surface members 2 and attachable and detachable through a movable engaging piece 7. When the sliding member 3 is inserted into the inside of the groove 4 of the wall surface member 2, the engaging piece 7 projects and engages with the engaging part 5 in the groove 4 to prevent the lowering of a slide block.
