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 |
