In addition, central protrusion portion 332 coordinates in front recess 252, track-type facilities 702 can be prevented with the first crook Swung centered on 331.Consequently, because left and right rail device 702 is parallel to each other, so moving guide rail is smoothly slided, make Obtain operating physical force when can reduce pull sliding door 201.

In addition, when track-type facilities 702 are configured in the lower section of the central portion of the above-below direction of sliding door 201, bin guide rail 222 rear end can easily insert the rear side of the bottom surface of storeroom from oblique upper.Therefore, it is possible to improve 702 pairs of track-type facilities In the disassembly of adiabatic main body 101.

Track-type facilities 702 are configured in the lower section of the central portion of the above-below direction of sliding door 201 so that the side of container 206 Major part have and do not form the even shape of convex-concave surface.In this way it is possible to reduce along the side of container 206 from front side The duct resistance of the cooling cold air moved to backside flow.As a result, it is possible to reduce to cooling fan（It is not shown）Input, and can Realize the energy-conservation of refrigerator 100.Because side is in even shape, design can be improved.When container 206 and sliding door 201 1 Rise when being extracted, the cold air in container 206 can be reduced and flowed out to outside container 206, i.e. to outside vegetable compartment 103, and can be real The energy-conservation of existing refrigerator 100.

In addition, therefore container 206 keeps bottom by door frame 305.Therefore, track-type facilities 702 will not be by the side of container 206 Space be divided into upper and lower part, and will not because of the temperature difference between top and the bottom or convection current air pocket generation, cause knot Dew or frosting.

Central protrusion portion 332 and front recess 252 can not be configured, and it is solid by the first crook 331 and rear recess 251 Determine track-type facilities 702.
