PURPOSE: To achieve a less thickness of a duct while increasing a strength by building a chilled air duct, provided inside a heat insulating material at a rear part of a freezing chamber, up of a foaming resin with a lower expansion ratio to supply chilled air to a vegetable chamber. CONSTITUTION: A chilled air supply path 26 for supplying chilled air to a vegetable chamber is so arranged that the chilled air from a chilled air path for the vegetable chamber and the chilled air after passing through a refrigerating chamber and an ice temperature chamber is sucked thereinto. The chilled air supply path 26 for the vegetable chamber is formed with a resin duct 26A being buried into a heat insulating material at a rear wall part of a freezing chamber 6. In this case, the duct 26A is arranged at a specified point between an inner case 2 where the freezing chamber 6 is formed and an outer case 3, namely, a position side by side with a cooling chamber 14 provided with a cooler 12 and formed integral being filled with a foamed heat insulating material. Here, the duct 26A is made of a foaming resin with a low expansion ratio. This enables an increasing in strength with a higher resin density to form the duct 26A having a required heat insulating property with a less thickness. |
