  The present invention relates to a refrigerator.

  2. Description of the Related Art Conventionally, in a refrigerator, a configuration is known in which the interior of a refrigerator main body constituting an outer shell is partitioned in a vertical direction by a partition member to form a plurality of storage rooms having different temperature zones. As an example, the storage room includes a refrigerator, a vegetable room, a freezer room, and the like. Each storage room may be provided with a storage case capable of storing an object to be cooled in consideration of usability. Moreover, the storage room door is provided in the front opening of each storage room of the to-be-cooled object. A door gasket for preventing cold air in the storage chamber from flowing out is attached to the storage chamber door along the inner periphery.

  In the refrigerator, indirect cooling from the refrigerator compartment may be enhanced by forming a thin plate thickness of the partition member that partitions the vegetable compartment and the refrigerator compartment. However, since the front side is the close contact surface of the door gasket, it is necessary to secure a thickness that allows the partition member to be in close contact with the door gasket, and there is a step between the thinned portion and the front side portion. There is a problem. In other words, in the refrigerator, if the storage case is sized according to the thin portion of the partition member, the stepped portion does not open due to an obstacle when the vegetable compartment door is pulled forward. Therefore, the storage case needs to be sized according to the thickness of the front side of the partition member. However, in the storage case, a large gap corresponding to a step is generated between the upper surface opening of the storage case and the lower surface of the thin portion of the partition member. As a result, moisture in the storage case escapes from the gap between the upper surface opening of the storage case and the lower surface of the partition member, and the freshness of vegetables and the like may be reduced.

  For example, in the storage disclosed in Patent Document 1, a freezer container that is a storage case includes a main container and an auxiliary container arranged to cover the upper surface opening of the main container, and the upper surface opening of the auxiliary container is covered with a lid. It is a configuration that directly closes. Since this storage block | closes the upper surface opening of a freezer compartment container with the lid | cover, the water | moisture content in a storage case can be hold | maintained and the freshness of vegetables etc. can be maintained.
