Japanese Patent No. 394 discloses a refrigerator inner box in which an insertion hole for mounting a component formed on a wall surface of the inner box is in a semi-processed state.

[0004]

In the partitioning device of the refrigerator described in the above and the above-mentioned publications, the partitioning plate is fixed to the partitioning of the inner box after foam filling of the heat insulating material. A sealing work must be performed to prevent the heat insulating material from leaking through the hole for mounting the partition plate formed in the partition, which causes a problem of poor workability. On the other hand, it is difficult to provide the insertion hole of the inner box described in the above publication in the above-mentioned partition because of the wall thickness. Even if the insertion hole is provided, it is necessary to penetrate the insertion hole with a claw or a locking piece formed on the partition plate, but since the insertion hole is in a semi-processed state, the insertion hole is penetrated. Therefore, it is necessary to apply external force to the partition plate. At this time, the external force must be concentrated on the claw or the locking piece,
The work is difficult to perform, and there is a risk that a dent may be formed on the front surface of the partition plate depending on how external force is applied, and it is unsuitable for application to the above or.

In view of the above, the present invention provides a refrigerator that facilitates the work of fixing the middle partition plate (referred to as the plate in the present invention) and does not require the work of sealing the heat insulating material of the middle partition portion (the front plate in the present invention). The purpose is to do.
