PROBLEM TO BE SOLVED: To provide a door operation assisting device having sufficient closing force for surely closing a door, and capable of gently closing the door.SOLUTION: A door operation assisting device 5 includes a cam member 51 provided in a refrigerator body 2, a turning cam follower supporting part 521 attached to a door 3, a turning cam follower 53 which can be relatively turned to the door 3 by turning of the turning cam follower supporting part 521 together with the door 3, a torsion coil spring 54 which can be integrally turned with the turning cam follower 53 and on which elastic energy energizing the door 3 to a close direction is accumulated, a cam surface 511 formed on the cam member 51 and having an energy accumulation region in which the elastic energy is accumulated on the torsion coil spring 54, and a braking member (oil damper) 55 connected to the turning cam follower 53 and generating a load when the door 3 is turned to the close direction.SELECTED DRAWING: Figure 4
【課題】確実な扉の閉塞動作を可能にするに十分な閉塞力を備えているとともに、緩やかに扉が閉塞動作する扉操作補助装置を提供すること。【解決手段】扉操作補助装置５は、冷蔵庫本体２に設けられたカム部材５１と、扉３に取り付けられた回動カムフォロア支持部５２１と、回動カムフォロア支持部５２１が扉３とともに回動することにより扉３に対して相対的に回動可能な回動カムフォロア５３と、回動カムフォロア５３と一体的に回動可能で、扉３を閉塞する方向に付勢する弾性エネルギが蓄積されるねじりコイルばね５４と、カム部材５１に形成され、ねじりコイルばね５４に弾性エネルギを蓄積させるエネルギ蓄積領域が形成されたカム面５１１と、回動カムフォロア５３に連結されて扉３を閉塞する方向に回転させる際に負荷を発生させる制動部材（オイルダンパ）５５とを備える。【選択図】図４
