摘要： PROBLEM TO BE SOLVED: To provide a vacuum heat insulator which can improve a handling performance of a core material, which can reduce electrical/thermal energy at the time of manufacturing, and which can reduce costs by the reuse of end materials which do not contain binders. SOLUTION: The core material 10a of the vacuum heat insulator 20 is made of fiber polymers, and the core material 10a is stored in the outer covering material 1 having gas barrier performance. The core material 10a is a laminated product constituted by superimposing a plurality of heat insulators, and is constituted by a heat insulator ba and one or a plurality of heat insulators ba3a, The heat insulator ba is cut in a plurality of pieces so that the laminated product has a required size. Then the heat insulators ba3a are provided to at least one side of the heat insulators ba3a cut into a plurality of pieces and retain the shape. An inner covering material ab2a, which contains the core material, and the heat insulators ba3a are laminated, and the heat insulators ba3b are made of fiber polymers which do not contain the binders. The vacuum heat insulator 20 is provided with the inner covering material ab2b covering the entire core material, and the outer covering material 1 containing the inner covering material ab2b is decompressed and is maintained under vacuum.

摘要： PROBLEM TO BE SOLVED: To solve the problem that although a thermal insulation box of a refrigerator is so constituted that a fitting part of an inner box is inserted in an outer box groove, and the space between an installed outer box and the inner box is filled with a foam thermal insulating material when the external dimension of the fitting part becomes smaller than the inner dimension of the outer box groove due to working variations of the respective boxes, the outer box and the inner box are dislocated, or the inner box is partially shifted inward with respect to the outer box, or the foam thermal insulating material leaks to the outside.
SOLUTION: In an inner box flange 17, a flange step 19 is formed in a position between the fitting part 18 and the outer box groove 15 to be locked on the an internal step 15d of the outer box groove 15.
