PROBLEM TO BE SOLVED: To make supportable shelf members stably without reducing the strength of the shelf members and to support shelf boards different in width in the depth direction. SOLUTION: First and second shelf receiving devices 14 and 15 are mounted on a pair of right and left supporting bodies 11 and 12, and a shelf board 17 is supported at each of the shelf receiving devices 14 and 15. Recessed parts 18 are provided at the end parts of the back surface of the shelf board 17, and dowels 30 to form protruding parts are provided in the supporting surfaces of the shelf receiving devices 14 and 15. By fitting the dowels 30 into the recessed parts 18, it is possible to support the shelf boards 17 stably. In addition, holes 35 for mounting dowels capable of changing mounting locations are provided at four front and rear locations in the supporting surface of the first shelf supporting device 14 corresponding to the separation distances of the recessed parts 18 in the back surfaces of first and second shelf boards 17A and 17B of different depth widths.
