PROBLEM TO BE SOLVED: To provide a structure of a cooling storage enabling to form a ventilation duct with small ventilation resistance reasonably. SOLUTION: The cooling storage 1 is cooled by a cooling cycle 100 including a Stirling refrigerator 101 as a component. A machine chamber 11 is formed on a back surface upper part of an outer shell 10 of the cooling storage 1. The Stirling refrigerator 101, a high temperature side condenser 112, and a condensing fan 114 are housed in the machine chamber 11. Air for radiation sucked from a ventilation space 12 on a lower part of the cooling storage 1 is sent via a rear part passage to the machine chamber 11. A resin molded duct 20a buried in an insulating layer 18 in the outer shell 10 forms a passage 20. The resin molded duct 20a is curved (bent) in response to positional relation with other part or changes a cross sectional shape locally. A lower part of the resin molded duct 20a is widened toward the ventilation space 12. COPYRIGHT: (C)2007,JPO&INPIT
