Abstract
An opening/closing device of a door for a refrigerator or the like will open/close the door member at a desired side, namely, at the right side or at the left side, without requiring a movable operating handle. The device is simple in construction, has a high adiabatic efficiency, and can be easily incorporated in the door member. Therefore, no special mechanism is necessary in the door member and no structural change is required inside the door member.
