5b, a guide groove 5c for sliding both ends of the rear crosspiece 3b of the front shelf 3 back and forth, and a guide plate 5d on which both ends of the front crosspiece 3a of the front shelf 3 are placed when the front shelf 3 is slid backward.
It is composed of etc. 6 is a decorative board that is fitted to the front crosspiece 3a of the front shelf 3.

To assemble the device composed of the above parts, the front shelf 3 and the rear shelf 4 are pot welded and coated separately, and then the front shelf 3 is installed below the rear shelf 4. 3 is disposed above the guide groove 6C of the shelf holder 5, and the holes 5a of the shelf holder are formed in the front holder 4a and the rear holder 4b of the rear shelf 4.
, 5b are press-fitted, a shelf device in which the front shelf 3 and the rear shelf 4 are integrated is completed.

Next, the state in which the shelf device is assembled into the refrigerator body will be explained using FIGS. 3 to 6. Reference numeral 7 denotes a refrigerator body, and 8 denotes a space inside the refrigerator, which is formed in the refrigerator body 7. Numeral 9 is a mesh shelf, and multiple shelves are installed inside the refrigerator to store food. Reference numeral 7a denotes a shelf supporting rib integrally formed from the inner wall of the refrigerator body 7, with a front shelf 3 installed at the front and a shelf support 5 at the rear. The shelf supporting ribs extending in the depth direction from the shelf supporting ribs 7a are part 7C.
and the guide groove 6c of the guide groove 6c provided integrally from the shelf support 5.
are placed overlapping each other. Further, in front of the guide groove 5c of the shelf support 5, an inclined guide protrusion 7b is formed continuously from the shelf support rib 7a and integrally projects upward from the shelf support rib 7a. It is fitted and protruded from the notch 5q.
