Here, the stopper 52 extends inward from the passage hole 47c of the engaging installation portion 47. Therefore, when the operation piece 42 is pressed while the locking piece 40 is blocked by the stopper 52, the locking piece 40 may be separated from the stopper 52 in cooperation with the operation part 42.

The spring member 60 is disposed below the locking piece 40 to press the coupling button 36 upward. Thus, when the user presses the release button 37, the coupling button 36 may be moved in the release direction by the elastic force of the spring member (60).

With this configuration, a process of assembling and separating the rail assembly 28 of the refrigerator 10 according to the present invention into the inner box 11 of the second auxiliary storage chamber 18 will be described in detail with reference to FIGS. 4A and 4B. Is as follows.

First, the worker screws (not shown) the side frame 26 of the second slide rail 32 and the second door assembly 23 to couple the second door assembly 23 and the rail assembly 28. . Thereafter, the rail assembly 28 is inserted into the support bracket 45 mounted to the second auxiliary storage chamber 18. After the guide rail 29 of the rail assembly 28 is inserted into the support bracket 45, the coupling rail 36 is pressed to maintain the guide rail 29 and the support bracket 45. At this time, the extension portion 39 of the coupling button 36 passes through the through holes 47b and 29b of the support bracket 45 and the guide rail 29, respectively, and the locking piece 40 is caught by the stopper 52. Movement of the guide rail 29 with respect to the support bracket 45 is prevented.

In order to separate the second door assembly 23 from the second auxiliary storage chamber 18, the release button 37 is pressed to release the coupling between the guide rail 29 and the support bracket 45. At this time, the engaging piece 40 is released from the stopper 52 by the pressing of the release button 37, the coupling button 36 is moved upward by the elastic force of the spring member 60. Therefore, the guide rail 29 can be slidably moved with respect to the support bracket 45 so that the second door assembly 23 can be pulled forward.

By such a configuration, the rail assembly can be easily mounted in the storage chamber.

In the above-described embodiment, the guide rail coupling portion is provided as a button, but the support bracket and the rail assembly are held or released, but the guide rail coupling portion may be provided as a screw, but is not limited thereto. Of course.

In the above embodiment, the support bracket and the rail assembly are held or released by the guide rail coupling portion, but when the rail assembly is directly coupled to the rail support portion without mounting the support bracket, the rail support portion and the rail assembly are coupled to each other. Of course, it can also be prepared. In this case, the guide rail coupling portion is provided in the rail support portion so that the rail assembly can be held or released from the rail support portion.

In the above embodiment, although the engaging button is pressed by the elastic force of the spring member, the engaging button itself may be provided with a rubber material, of course.

In the above-described embodiment, only the case of the second auxiliary storage chamber and the second door assembly has been described, but the same may be applied to the first auxiliary storage chamber and the first door assembly.

In the above-described embodiment, a refrigerator having a plurality of storage compartments has been described as an example, but it can be applied to the refrigerator having a single storage compartment.

In the above-described embodiment, the first auxiliary storage chamber and the second auxiliary storage chamber are provided as auxiliary refrigeration chambers and auxiliary refrigeration chambers, respectively, but may be provided as a vegetable compartment capable of maintaining a storage temperature of vegetables or fruits, but are not limited thereto. Of course it can.
