PROBLEM TO BE SOLVED: To achieve miniaturization and simplification of a door operation assisting device for assisting operation for closing an opening with a door or the like.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, and a cam surface 511 provided on the cam member 51 and having an energy accumulation region in which the elastic energy is accumulated on the torsion coil spring 54. When the door 3 is turned to an open direction, the turning cam follower 53 is turned while being brought into contact with the energy accumulation region 5111 formed on the cam surface 511, and the elastic energy energizing the door 3 to the close direction is accumulated on the torsion coil spring 54.SELECTED DRAWING: Figure 4
【課題】扉等によって開口を閉塞する操作を補助する扉操作補助装置の小型化および簡易化を実現すること。【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、を備え、扉３を開放する方向に回動する際、回動カムフォロア５３が、カム面５１１に形成されたエネルギ蓄積領域５１１１に接触しながら回動し、ねじりコイルばね５４に扉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。【選択図】図４
