Leaks into the freezer 2. Instead of the warm air, the cool air in the freezing compartment 2 flows below the counter flow path 28 into the space 27 and cools the partition plate 22. The exchange of warm air and cold air passing through the counter flow path 28 causes a decrease in the cooling efficiency of the refrigerator. Therefore, if the amount of switching between the warm air and the cool air is reduced, the cooling efficiency of the refrigerator can be reduced.

できる。In the present embodiment, when the door 8 is closed, even if the projections 25 and 26 are closest to the seal fin 12a,
By forming only a small gap such that they do not contact each other, the counter flow path 28 is narrowed, and the amount of the exchange between the warm air in the space 27 and the cool air in the cooling chamber 2 described above does not include the protrusions 25 and 26. Since it is greatly reduced as compared with the case, it is possible to mitigate a decrease in cooling efficiency.
In addition, since the cooling effect of the cold air flowing from the inside of the freezing compartment 2 of the middle partition plate 22 is reduced, the occurrence of dew condensation on the portion of the middle partition plate 22 that comes into contact with the outside air can be suppressed. Although FIG. 2 shows a case where two narrow rib-shaped protrusions having different lengths are provided, by increasing the number of protrusions,
The amount of cool air flowing into the space 27 can be further reduced.

By enclosing, the heat insulation effect near the space 27 increases,
It is possible to further reduce the decrease in cooling efficiency.
