ICE STORAGE

To provide an ice storage capable of suppressing intrusion of abrasion powder generated due to sliding between an outer door and an inner door thereinto.SOLUTION: A facing surface of an outer door 17 facing an inner door 18 is provided with a first surface part 23 with which a tip part 19a of the inner door 18 can be in contact, and a second surface part 24 with which a projection part 19b separated from the tip part 19a of the inner door 18 can be in contact. In the first surface part 23 and the second surface part 24, a first state in which the tip part 19a is in contact with the first surface part 23 and the projection part 19b is separated from the second surface part 24, and a second state in which the projection part 19b is in contact with the second surface part 24 and the tip part 19a is separated from the first surface part 23 are switched while the outer door 17 is rotating.SELECTED DRAWING: Figure 3 【課題】外扉と内扉との摺動により発生した摩耗粉が庫内に侵入するのを抑制し得る貯氷庫を提供する。【解決手段】外扉１７における内扉１８と対向する対向面に、内扉１８の先端部１９ａが当接可能な第１面部２３と、内扉１８の先端部１９ａから離間する張出し部１９ｂが当接可能な第２面部２４とが設けられる。第１面部２３および第２面部２４は、第１面部２３に先端部１９ａが当接すると共に第２面部２４から張出し部１９ｂが離間する第１の状態と、第２面部２４に張出し部１９ｂが当接すると共に第１面部２３から先端部１９ａが離間する第２の状態とが、外扉１７を回転する途中で切り替わる。【選択図】図３
