PROBLEM TO BE SOLVED: To easily and surely determine existence of a fitting failure of structural parts to be fixed to an inner plate, coming in contact with each other, inside of a front door with a visual inspection from outside after assembling the structural parts. SOLUTION: A magnet 26 for an opening sensor fixed to the inner plate 2, coming in contact with each other, is provided inside of the front door 14 formed by filling a heat insulating material 5 having the foaming property in a space formed between the inner plate 2, an outer plate 3 and a frame plate 4. A gas discharge hole 24 is provided through a magnet fixation part 21 to discharge the gas to be generated by foaming of the heat insulating material 5 when fitting of the magnet 26 is failed outside through the gas discharge hole 24.
