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.

A refrigerator comprising:
- an outer box formed from a top face plate, a bottom face plate, a right-side plate, a left-side plate and a rear face plate, a front face having an opening therein being defined by the top plate, the bottom face plate, the right-side plate and the left-side plate, and an outer box flange portion being provided along an inner side of each of the right-side and left-side plates;
- an inner box positioned within the outer box, the inner box having an inner box flange portion projected outwardly along a peripheral edge thereof around an opening formed in a front face of the inner box, the inner box flange being inserted between each of the outer box flange portions to engage the inner and outer boxes;
- a space being defined between the inner and outer boxes with an adiabatic material filled therein;
- at least one compartment wall for dividing a space in the inner box into a plurality of chambers, the compartment wall having a front face;
- a compartment reinforcing a plate for each of the compartment walls, the compartment reinforcing plate being mounted on the front face of each compartment wall;
- and
- a plurality of compartment fixing plates, at least one compartment fixing plate being operatively connected to the right-side plate of the outer box and at least one compartment fixing plate being operatively connected to the left-side plate of the outer box, the inner box having an opening for each of the fixing plates, the fixing plates extending through the openings defined in the inner box and being secured to the compartment reinforcing plate in order to hold the at least one compartment wall in position.
