This supporting frame 4 is attached to the connecting frame 2 by fitting its front and rear ends into the notches 6, 6 in the connecting frame 2, and bringing its end surface into contact with the inner surface of the vertical piece 2a of the connecting frame 2. It is steadfastly supported.

Reference numeral 13 denotes a horizontal base plate, and reinforcing rods 14, 14 facing in the left-right direction and forming two rows of front and back are fixed to the lower surface of the base plate. It is placed on the underframe 1 so as to engage inside the protrusion.

In the base plate 13, insertion holes 15 to 18 having the same shape and size as the holes are provided at positions corresponding to the respective fitting cylinders 9 to 12.
are drilled, and the columns 19 to 22 are inserted into the respective fitting cylinders 9 to 12 through these insertion holes 15 to 18, respectively.
By fitting into the support columns 19 to 22, each support column 19 to 22 is firmly supported.

The pillars 19 and 20 arranged on the left and right support the intermediate back plate 23, and the supports 21 and 22 arranged on the front and back support the intermediate back plate 23.
supports the side back plate 24. The intermediate back plate 23 is arranged so as to intersect with the side back plate 24 in a T-shape in plan view, and the upper ends of the intersection of both back plates 23 and 24 are fitted with appropriate clasps 25. are connected to each other.

Reference numeral 26 denotes a shelf board supported at a desired height by supporting arms (not shown) that are fixed to appropriate heights of each of the pillars 19 to 22.

In the present invention, each of the support columns 19 to 22 is fitted into the fitting tubes 9 to 12 in the underframe 13 through the insertion holes 15 to 18 bored in the base plate 13, so that the base plate 13 is They are securely positioned and fixed to the frame 1, and no coupling tools are required for their mutual connection.

In addition, the reinforcing rods 14, 14 on the lower surface of the base plate 13 are
By engaging with the upper end protrusions of the pillars 3e and 3e, respectively, the positioning of the base plate 13 is ensured, and furthermore, the alignment of each of the insertion holes 15 to 18 in the base plate 13 with the corresponding fitting cylinders 9 to 12 is ensured. This is advantageous because it facilitates the insertion of the strut.

Furthermore, since both ends of the support frame 4 are fitted and locked into the notches 6 in each connection frame 2, the support frame 4 does not move forward, backward, left or right, and moreover, the support frame 4 is connected to the underframe.
