Description

refrigerator

The present invention relates to a refrigerator, and more particularly to a refrigerator having a structure for supporting a rail provided on a door of a storage room.

Various refrigerators that have a drawer-type door have been proposed (see, for example, Patent Document 1). A movable rail that moves in the front-rear direction is attached to the door. A roller that moves on a fixed rail fixed to the storage chamber is provided at a lower portion of the movable rail. Moreover, the flange supported by the support structure rotatably attached to the storage chamber is formed in the upper part of the movable rail. In addition, the fixed rail of patent document 1 is integrally shape | molded by the partition member which partitions off a storage chamber.

Here, the lateral side surface of the storage container is tapered. The lateral side surface of the storage container is disposed closer to the center of the storage chamber in the lateral width direction of the storage chamber than the support structure. For this reason, if the vertical position of the support structure is low, the upper portion of the storage container does not need to be disposed closer to the center of the storage chamber in the lateral width direction of the storage chamber than the support structure. That is, if the vertical position of the support structure is low, the upper portion of the storage container may be disposed on the upper side of the support structure. Therefore, if the vertical position of the support structure is low, the volume of the storage container can be suppressed from being reduced. In the refrigerator described in Patent Document 1, since the rotatable support structure is located on the lower side of the storage chamber, it is possible to suppress a reduction in the volume of the storage container.
