PROBLEM TO BE SOLVED: To improve expandability and contractibility without lowering heat insulation, by setting a thickness of a site of a partition wall to be applied by a tensile force to a specific range when a door of air chambers divided by a plurality of partition walls is opened. SOLUTION: Since a site of a partition having a thickness is disposed at a site to be applied by a tensile force when a refrigerator door 3 is opened, an overall thickness of the partition wall applied by the force when the door 3 is opened is set to 0.7 to 2.5 mm. If the thickness is less than 0.7 mm, when the door 3 is opened, a thin part of a magnet packing 4 is excessively elongated, and the door is not smoothly opened. If it exceeds 2.5 mm, its expandability and contractibility become insufficient so that a sealing function is lowered. Thus, the pacing having suitable expandability and contractibility can be obtained without lowering the heat insulation.
