The front wall can be made lower. As described above, in a configuration in which one of the ice storage container 8 and the housing member 100 is pulled forward, the other is not pulled out together with it, the housing member 100 is moved forward to take out the automatic ice maker 7 to the front of the refrigerator. When the cup ice 123 is pulled out, the right end of the frame-shaped portion 101 may push the cup ice 123 or the like forward depending on how the cup ice 123 or the like is stacked.

In order to prevent this, a relatively large curved surface (R surface) 12 is provided on the right side of the front end of the frame-like portion 101.
5 is formed. The curved surface (R surface) 12 is obtained by pulling the housing member 100 forward.
Even if 5 hits the cup ice 123 or the like, the cup ice 123 or the like slides along the curved surface (R surface) 125 to escape, so that the cup ice 123 or the like is not pushed forward.

Further, the left and right end portions of the housing member 100 are placed on the support portion 104. In order to prevent water droplets adhering to this portion from freezing and being unable to pull the housing member 100 forward, The contact area between the left and right end portions of the member 100 and the support portion 104 is reduced. In the figure, protrusions 126 projecting laterally and downward are formed at the left and right ends of the housing member 100, but the upper and side surfaces of the support portion 104 corresponding to the left and right ends of the housing member 100 are directed toward the housing member 100. It is also possible to use a method of forming protruding protrusions.
