The gap between the front opening and the edge of the front opening is hermetically closed. That is, in the refrigerator, the closing member 16
The gaps between the upper and lower ends and the upper and lower edges of the front opening of the cabinet main body 11 are hermetically and reliably closed by the guide members 21 and 22 and the seal member 23.

When the first door 12 is closed in the refrigerator, the guide member 21 on the closing member 16 side of the guide mechanism 20 is closed.
Is operated by the action of the torsion spring 19b.
It resiliently contacts the guide member 22 on one side. For this reason, when the first door 12 is opened, the guide member 21 rotates the closing member 16 gradually inward while sliding on the guide member 22. When the guide member 21 is separated from the guide member 22, the closing member 16 rotates further inward to rotate the mounting portion 18 of the movable hinge portion 18 a of the hinge 18.
The opposing surface of a2 is attracted to the attracting magnet 19a and held on the first door 12 side.

In the refrigerator, a torsion spring 19b for urging the closing member 16 inward is provided between the first door 12 and the closing member 16.
Even when the first door 12 is closed with an excessive force, the closing member 16 does not collide with the inner surface of the second door 13 that has already been closed, and damage to the closing member 16 due to severe collision is prevented. At the same time, when the first door 12 is opened, the closing member 16 is smoothly rotated inward by the urging force of the torsion spring 19b and retreats from the front end of the first door 12. Further, in the refrigerator, the magnet 1 for attracting the closing member 16 turned inward to the first door 12 side.
Since the closing member 16 is provided, the closing member 16 is fixed by suction to the first door 12 when the closing member 16 turns inward, so that the closing member 16 collides against the first door 12 when the closing member 16 turns inward. There is no such thing as repeated bouncing.

By the way, in the mounting structure of the guide member 22 in the refrigerator, the fixing plate 25a is previously positioned by the cushion body 25b, and the screw hole 25a1 of the fixing plate 25a is closed when the heat insulating material 11d is foamed. Therefore, the work of attaching the guide member 22 is performed favorably. The guide member 22 is connected to the connecting member 1.
Since the flat plate portion 11c2 of the guide member 1c is mounted while being strongly sandwiched together with the fixing plate 25a, the mounting strength of the guide member 22 is high and the mounting state is extremely stable.

In this embodiment described above,
Although the example in which the guide member 22 is attached to the cabinet main body 11 has been described, it is needless to say that the attachment structure according to the present invention can also be adopted for attaching a fixed member attached to the cabinet main body 11 other than the guide member 22. In the present embodiment, the first
A U-shaped sealing member 12d is detachably attached to the rear surface of the door 12, and an I-shaped sealing member 16e is detachably provided on the front surface of the closing member 16, so that each of these sealing members 12d, Although an example has been shown in which the closing member 16 is not hindered in the removal and attachment during replacement or cleaning of the 16e, the present invention provides the first door 12 with the second door 1
Similarly to 3, the present invention is also applied to a normal refrigerator having a square-shaped seal member detachably mounted. Also,
In the present embodiment, the guide mechanism 20 having the seal member 23 is employed, and the upper and lower ends of the closing
Although an example has been shown in which the gaps between the upper and lower edges of the front opening 1 are securely sealed, the present invention employs various types of conventionally known guide mechanisms in place of the guide mechanism 20 in the usual manner. Also applies to refrigerators.
