According to the configuration of the above embodiment, the left and right rear wall panels 3.3 joined in a straight line to each other are:
The ridge 17 of the vertical frame 9 of one panel 3 and the other panel 3
When fitting into the concave groove 26 of the vertical frame 10, since the fin-shaped pieces 22 of the ridge 17 are elastically in contact with both inner sides of the concave groove 26, the fins 17 come out of the cooler 6 toward the inside of the refrigerator. Good airtightness can be ensured so that cold air does not leak to the outside from between the joining surfaces of the vertical frames 9 and 10 of the panels 3 and 3.

The fin 22 is inclined with respect to the ridge 17 so that the tip 22a of the fin 22 is directed toward the base 19 on the lower side in the insertion direction. Since 22 stands upright, a retaining effect can be obtained.
Since both sides of the inside of the concave groove 26 are inclined outwardly,
Also in this respect, the ridge 17 can be easily fitted into the groove 26.

In the rear wall panel 3 and the left and right side wall panels 2 which are joined orthogonally to each other, the ridges 17 of the vertical frame 9 of the rear wall panel 3 and the vertical frame 34 of the side wall panel 2 are formed. When the concave groove 26 is fitted into the concave and convex, the rear wall panels 3 and 3 described above are formed.
The fin-shaped pieces 22 are made to elastically contact both sides of the inside of the concave groove 26 in the same manner as in the joint portion of FIG.
-Airtightness can be provided between the bonding surfaces of the 34. Also in this case, the fin-shaped piece 22 is provided in the inclined shape so that the tip 22a of the fin-shaped piece 22 faces the base 19 on the lower side in the insertion direction. The fact that the fin-shaped pieces 22 stand upside down so that the retaining effect can be enhanced is the same as in the case of the left and right rear wall panels 3.3 joined to each other in a straight line.

By fitting the bottom ridges 29 of the left and right side wall panels 2 between the two projections 20 of the ridges 17 of the rear wall panel 3, the panel 3 is oriented in the panel thickness direction. The displacement of the panel 2 in the direction orthogonal to the panel thickness direction can be restricted, and the panels 3 and 2 can be joined at right angles.

Panel 3 and ceiling panel 4, left and right side wall panel 2 and ceiling panel 4, rear wall panel 3 and floor panel 1, and left and right side wall panel 2 and floor panel 1. The same can be said for each.

[0038] Since the first and second corner stoppers 47, 50 attached stop from the inside of each panel 1, 2, 3 and 4, the wall W _1, W ₂ and earthen F perpendicular houses 9 It can be assembled in the corner where the two meet, or in the corner of the garden, so that there is no need to assemble and transport it to another place.

The corner stopper 50 is formed in a shape having a wall 50a in addition to the walls 50b and 50c connected at right angles to each other so that three panels perpendicular to each other, for example, for a rear wall. Advantageously, the corners where the panel 3, the left and right side wall panels 2 and the ceiling panel 4 (or the floor panel 1) intersect can be fastened with a single corner stopper 50. The fin 2
In the case where No. 2 is not provided, airtightness may be imparted by using a caulking agent.
