BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of preventing the movable shelf member from being moved from the use position to the retracted position arbitrarily.

Generally, a refrigeration cycle includes a compressor for compressing a refrigerant at high temperature and high pressure, a condenser that receives the compressed refrigerant from the compressor and condenses it into a liquid phase, and an evaporator that uses latent heat of evaporation to vaporize the liquefied refrigerant to cool the air in the refrigerator. Consists of a series of repetitive cycles.

A refrigerator is a home appliance that forms cold air based on such a freezing cycle, and includes a main body divided into a freezer compartment that forms relatively low temperature and a refrigerator compartment that forms a relatively high temperature as compared to the freezer compartment, and a freezer compartment that opens and closes the front openings of the freezer compartment and the refrigerator compartment. It is generally composed of doors and refrigerator doors. In addition, the inside of the freezer compartment and the refrigerating compartment is provided with a plurality of nearly rectangular plate-shaped shelves for storing food and partitions the freezer compartment and the refrigerating compartment up and down, and both sides of the inner wall of the freezer compartment and the refrigerating compartment protrude from the inside in the horizontal direction in the front and rear directions. Ribs are formed to contact and support the edges of the lathe.

On the other hand, in recent years, except for the lowermost shelf device among a plurality of shelf devices, a shelf device capable of retracting a part of the shelf device from the front of the cooling chamber to the rear when it is necessary for storing bulky foods has been adopted. .
