PROBLEM TO BE SOLVED: To facilitate the vertically lengthwise and crosswise expansions of a display area according to the sales of commodities and eliminate the dead space to effectively display the commodities. SOLUTION: This joint rack for commodity sales display is formed of at least two or more required number of tray bodies 1 and at least four or more required number of protrusively curved struts 2. The tray body 1 is formed into a square flat part 3 of a required thickness having outside semicircular corner parts 1a, 1b, 1c, and 1d at four corners, and a circumferential wall part 4 raised in a required height upward and downward along the periphery of the square flat part 3 and formed in a required thickness so as to have a T-shaped side sectional form. Strut lower end receiving holes 5a, 5b, 5c, and 5d for fitting and supporting the lower ends of the struts 2, respectively, are formed on the four corner upper surfaces of the flat part 3. Vertical guide grooves 6a, 6b, 6c, and 6d for continuously connecting and supporting the lower end outer surfaces of the struts 2 are formed in a recessed shape on the four corner inner surfaces of the circumferential wall part 4 so as to be connected to the strut lower end receiving holes 5a, 5b, 5c, and 5d. Connecting leg parts 8a, 8b, 8c and 8d having strut upper end receiving holes 7a, 7b, 7c, and 7d for fitting the upper ends of the struts 2 opened at the lower ends are protrusively formed on the four corner lower surfaces of the flat part 3. A connecting engagement recessed part 9a, 9b and a connecting engagement protruding part 10a, 10b, which are vertically slid and connected to each other, are formed on the outer surface of each corresponding edge of the circumferential wall part 4.
