<p><P>PROBLEM TO BE SOLVED: To provide a heat insulation apparatus for an automatic vending machine in which a heat insulation performance is prevented from being reduced by instability in quality and working efficiency is prevented from being reduced by requiring much working time. <P>SOLUTION: A heat insulation apparatus comprises a plate-like back heat insulator 4A disposed inside the back of an outer wall 3, and plate-like neighboring-face heat insulators 4B and 4C disposed on a side face and a top surface or a bottom surface of an outer wall adjacent to the back of the outer wall 3. In at least either one of rear end portions of the neighboring-face heat insulators 4B and 4C and an end portion of the back heat insulator 4A in opposite thereto, a portion with the elastic modulus partially smaller than that of the other portion is integrally formed and provided by such as integrally forming a projection 5 which is protruded toward the opposite heat insulator 4 and abutted thereto while being elastically deformed. Since the projection 5 is formed integrally with the heat insulators 4, no skill is required to workers and furthermore, assembly of heat insulators can also be performed easily within a short time. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
