PROBLEM TO BE SOLVED: To ensure high cooling efficiency and prevent deterioration of quality of a stored matter by obtaining an evaporation temperature suitable to cooling of a cooling chamber and an evaporation temperature suitable to cooling of a freezing chamber. SOLUTION: A three-way valve 14 is provided in a branch part S of a refrigerant passage formed on the refrigerant flowing-directional downstream side of a capillary tube 11. The three-way valve 14 is integrated with a variable throttle 15 changing the narrowing amount of the refrigerant carried into one side of the refrigerant passage after branched. According to switching of the three-way valve 13 (switching of the refrigerant passage), the narrowing amount of the refrigerant by the variable throttle 15 is changed. COPYRIGHT: (C)2007,JPO&INPIT
