<P>PROBLEM TO BE SOLVED: To provide a cooling chamber having a notation section enabling three-dimensional comprehension of a buried position of vacuum heat insulation materials, and achieving a high work efficiency when disassembling it. <P>SOLUTION: The cooling chamber has: an outer shell portion in which at least a part of vacuum heat insulation materials is buried; and a notation section 21 informing a buried position of the vacuum heat insulation materials. In the notation section 21, notation only by characters indicating the outer shell portion where the vacuum heat insulation materials are buried is performed wherein the characters in a layout and angle corresponding to the buried site are used so that three-dimensional position of the site is represented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
