PROBLEM TO BE SOLVED: To prevent narrowing of a space in the chamber of a refrigerating chamber 4 and prevent a ceiling duct 35 from being deformed due to its heat even when the lighting state of a chamber lamp 81 is continued. SOLUTION: A chamber light 81 is situated in the ceiling duct embedded in the ceiling of the refrigerating chamber 4. The lamp of the chamber light 81 is cooled by cold air supplied through the ceiling duct 35. This constitution prevents a chamber from being narrowed by reducing an protruding space of the chamber light 81 in the refrigerating chamber 4, and prevents thermal deformation of the ceiling duct 35 due to the heat of the lamp even when the chamber light 81 is always lit as a failure of the switch. |
