PROBLEM TO BE SOLVED: To perform an efficient transmission of power force of a motor to a door and make a compact size of the motor.SOLUTION: This invention relates to a door opening or closing mechanism 100 for a refrigerator comprising a motor provided at a housing H side of the refrigerator and a link mechanism 20 for transmitting a power force of the motor to a door D of the refrigerator so as to open or close the door D and to assist an opening of the door D. The link mechanism 20 has a first arm 21 for receiving a power force of the motor and rotated and a second arm 22 including a force point receiving force from the first arm 21 and a point of action adding force to the door D. Under a state in which the door D is closed, the point of action is positioned at a side of a rotating shaft T3 of the door D rather than a direction perpendicular to the door D as seen from the force point.SELECTED DRAWING: Figure 9 【課題】モータの動力を効率良く扉に伝えるようにして、モータの小型化を図る【解決手段】冷蔵庫の筐体Ｈ側に設けられたモータと、モータの動力を冷蔵庫の扉Ｄに伝達するリンク機構２０とを具備し、扉Ｄを開閉するとともに扉Ｄを開くための補助をする冷蔵庫用扉開閉機構１００であって、リンク機構２０が、モータの動力を受けて回転する第１アーム２１と、第１アーム２１からの力を受ける力点及び扉Ｄに力を加える作用点を有する第２アーム２２とを有し、扉Ｄが閉じている状態において、作用点が、力点から視て前記扉Ｄへ垂直に向かう方向よりも前記扉Ｄの回転軸Ｔ３側に位置するようにした。【選択図】図９
