PROBLEM TO BE SOLVED: To increase certainty of a door opening action, and to control a door opening angle of a refrigerator provided with a door opening device, and a controller controlling its actions. SOLUTION: When a touch switch 5 provided on a door 2 front face of the refrigerator 1 is operated, an input signal of the touch switch 5 is inputted, and a normal rotation voltage is applied to a motor 7. A door pressed part 6 is pushed away by an advance action of an output shaft 8 to open the door 2. It is confirmed that an angle of the door 2 detected by a volume 13 becomes a predetermined angle D2 from an angle D1 of a door closed state. A reverse rotation voltage is applied to the motor 7, an ON signal of a reverse end limit switch 11a is confirmed, and limit operation of the door opening device is executed and concluded.
