Description

  The present invention relates to a refrigerator having a configuration in which a drawer-type door is supported by a rail portion provided in a vertical partition.

  In the refrigerator, for example, an ice making room and a switching room in which a set temperature can be switched are partitioned by a vertical partition as a storage room. In these storage rooms, by pulling out the drawer type door from the storage room, it is possible to facilitate the removal of ice or food contained in a storage container attached to the drawer type door.

Such a drawer-type door is configured by supporting a door support portion attached to the drawer-type door with a rail portion integrally formed on the side surface of the storage chamber. In this case, as a structure for supporting the door support portion by the rail portion, a door support portion is provided on the upper surface of the partition cover portion covering the front surface of the bottom plate portion of the storage chamber, and the lower side portion of the door support portion is supported by the door support portion. At the same time, the storage container pulled out from the storage chamber is supported by supporting the roller provided at the rear end of the door support portion with the rail portion (see Patent Document 1).
