To provide an ice storage facilitating detachment and mounting work of a door unit.
The door unit 20 arranged in a casing includes: a body frame 28 forming an opening 28a; and slide doors 32, 34 slidably arranged in the body frame 28 and opening/closing the opening 28a. A clearance 64 opened on an ice storage chamber side is formed between a lower rail 46 arranged in a lower frame part 38 of the body frame 28 and supporting lower ends of the slide doors 32, 34 and the lower frame 38. An insertion part 68 capable of being inserted/detached to/from the clearance 64 is formed in a slope member 66. Insertion holes 68a or notches 68b corresponding to through-holes 60 of the lower rail 46 are formed in the insertion part 68. With the insertion part 68 inserted to the clearance 64, screws 52 inserted to the through-holes 60 are inserted to the insertion holes 68a or the notches 68b and are screwed to screw holes of a fixation member of the lower frame 38. Thus, the insertion part 68 is nipped between the lower rail 46 and the lower frame 38.
