PROBLEM TO BE SOLVED: To provide a cold air shutter that can perform individual cold air adjustment of multiple different chambers in one operation.SOLUTION: According to a cold air shutter of the present embodiment, an opening change rate Rf of an opening forming unit for freezing cold air is set to be different from an opening change rate Rr of an opening forming unit for refrigeration cold air, so that the independent adjustment of an opening area formed in both chambers becomes possible though both opening forming units have an interlocking mechanism. Accordingly, the cold air shutter can provide different amounts of opening adjustment, respectively, concerning the opening forming unit for the freezing cold air and the opening forming unit for the refrigeration cold air, while being one adjustment operation. |
