PROBLEM TO BE SOLVED: To prevent easily and surely the dew condensation of a glass door under the condition of installation, which permits the vapor condensation readily, by a method wherein the door, closing the opening of an insulating box body openably and slidably, is constituted of an insulating wall, whose peripheral thickness is formed so as to be thin, and a door sash, engaged with the peripheral part of the insulating wall. SOLUTION: Two pieces of left and right double sliding doors 21, 22 are attached to the upper surface opening of a storage chamber 7 (insulating box body 6) to close the storage chamber 7 openably. Two stages of upper and lower rails 24, 26 are formed on an inner box 3, positioned at the front and rear rims of the opening of insulating box body 6, while the doors 21, 22 are attached slidably to the rails 24, 26 respectively. These doors 21, 22 are constituted of insulating walls 27, 28 and peripheral door sashes 29, 31. Inner and outer surface members 33, 34, positioned at the peripheral rim of the insulating wall 27, are approached mutually to form a thin part 27A, pinching only a buffer member 37, while the thin part 27A of the insulating wall 27 is engaged with the engaging groove 29A of the door sash 29. |
