PROBLEM TO BE SOLVED: To prevent heat exchange efficiency of an evaporator from being lowered and further prevent frost from being clogged on one side of a lower part of the evaporator by guiding return cold air returned to the one side of the lower part of the evaporator after circulation in a chamber to the lower part of the evaporator substantially equally. SOLUTION: A shade 6' of a defrosting heater 6 provided on a lower part of an evaporator 5 is connected with an outlet 7a of a circulation passage 7 for circulating return cold air (b) from a vegetable chamber and a refrigeration chamber at its one side.
