PROBLEM TO BE SOLVED: To provide a door opening/closing mechanism capable of reducing torque of a motor necessary for cancelling magnetization between a door and a housing.SOLUTION: A door opening/closing mechanism for a refrigerator includes: a motor M configured to output power for opening/closing the door; a power transmission mechanism 40 configured to transmit power of the motor M to a hinge by rotation of a plurality of drive gears 45; and an auxiliary mechanism 30 configured to generate auxiliary force for moving the door at a closed position toward an open direction. The door opening/closing mechanism is configured to generate the auxiliary force of the auxiliary mechanism 30 by power of the motor M, before transmitting the power of the motor M to the hinge Z through the power transmission mechanism 40.SELECTED DRAWING: Figure 34 【課題】扉と筐体との着磁を外すために必要なモータのトルクを低減させることのできる冷蔵庫用扉開閉機構を提供する。【解決手段】扉を開閉するための動力を出力するモータＭと、モータＭの動力を複数の駆動ギア４５の回転によってヒンジに伝達する動力伝達機構４０と、閉塞位置にある扉を開方向に移動させるための補助力を発生させる補助機構３０とを具備し、モータＭの動力が動力伝達機構４０を介してヒンジＺに伝達されるまえに、モータＭの動力によって補助機構３０に前記補助力を発生させるように構成した。【選択図】図３４
