PROBLEM TO BE SOLVED: To provide a refrigerator capable of preventing inflammation and explosion to a refrigerant by immediately controlling a system of the refrigerator in the case when more than constant vibration due to an earthquake, etc., takes place at the time of operating the refrigerator to use combustible gas as the refrigerant. SOLUTION: This refrigerator using the combustible gas as the refrigerant operates when a vibration detection sensor 21 detects vibration due to the earthquake, etc., and detects that a detected vibrational value Sk is higher than a previously set vibrational value S, a control device 19 receiving its signal controls to automatically stop operation of a part having an electric contact point, gas leakage detection is carried out by a gas detection sensor 20 after specified time (t) passes, when it can confirm there is no gas leakage, the control device 19 automatically controls to re-input the electric power source of the part having the electric contact point so as to return to the normal operation by the signal of the control device 19 receiving a gas leakage signal and continues a driving stop state of the part having the electric contact point in the case when there is the gas leakage in the refrigerator to use the combustible gas as the refrigerant.
