As shown in the refrigerator, the refrigerating chamber 1 is positioned above and the freezing chamber 2 is positioned below. In particular, the refrigerating chamber is a French-type refrigerator in which a partition wall separating the interior is not formed.

The refrigerating chamber (2) has a door (3) for opening and closing the structure of the two-door open type, the circumferential surface of each door (3) is provided with a gasket (10) in close contact with the refrigerator main body (5) so that cold air does not leak out do.

In particular, the gasket 11 is installed so that cold air does not leak to the part where the doors 3 meet each other. In general, a refrigerator of a French type is provided with a filler on one door so that the gaskets of both doors are in close contact with each other. It has a structure or a fillerless structure in which the gaskets 11 of both doors 3 are in close contact with each other without a filler.

1 and 2 illustrate a pillarless type, in which the gaskets 11 provided on both doors are in close contact with each other while the doors 3 are closed, as shown in FIG. 1. Seal the gap.

3 is a cross-sectional configuration view in the direction A of FIG. 1 showing a state in which the gasket 11 is in close contact with both the doors 3 closed, and the gasket 11 has both doors 3 mutually connected to each other. It consists of the gasket holder 12 provided in the opposing side surface, and the gasket rubber 13 attached to this gasket holder 12, and mutually in close contact.
