Abstract: A height of a rack container or shelf is shiftable with an easy procedure and slight effort, to improve user friendliness even when disposed at quite a height from the floor within a storage chamber or compartment. An adverse effect on a downward adjacent shelf is avoided to improve or retain actually usable volume on the adjacent shelf. A rack apparatus or a refrigerator includes stationary rails, a traveling rail, arms hinged on a traveling rail to be turnable in one way or other, a rack support connecting the arms, and a rack container supported on the rack support. The rack container can be shifted forward by the traveling rail and be shifted upward and downward with keeping its horizontal posture, by turning of the arms.

Abstract: A refrigerator stated is characterized in that it includes a machine room (14) formed on a lower part of a rear of a main body of the refrigerator; a refrigerant compressor (12) installed offset to one side in the machine room (14) in a width direction; and a cooler (9) for receiving a refrigerant from the refrigerant compressor (12) and cooling an inside of a storage chamber; wherein the cooler (9) is arranged inside the refrigerator via a heat insulating wall (3a) of the main body above the refrigerant compressor (12) arranged on one side of the machine room (14) and at a position on an opposite side of the refrigerant compressor (12) in a width direction; and control and power source boards (21) of the refrigerator are arranged in another wide space of the refrigerant compressor (12) in the machine room (14) in a width direction.
