PROBLEM TO BE SOLVED: To save energy by reducing heat entering from an external part, in heat insulating constitution of a refrigerator. SOLUTION: A heat insulating door 46 is openably situated at the front opening part of a heat insulating box body 39, having a storage chamber 55 constituted at its internal part and the thickness of the heat insulating wall of a planar part 51 of the heat insulation door positioned opposite to a planar part 41 of the front edge of the heat insulating box body is decreased to a value lower than the reference heat insulation wall thickness of the heat insulating door 46 fronting on the interior of the refrigerating chamber 55. The front end part of the heat insulating box body 39 is cut through the reference wall thickness of the heat insulating door 46 and the distance of a throat 59 consisting of the front side of an inner box 44 and the outer side of a door inner plate 48 is lengthened, and penetration of outside air heat is decreased and energy is saved. |
