PROBLEM TO BE SOLVED: To facilitate cleaning without causing a cleaning tool from being caught by an open end extending longitudinally of a shelf reception member. SOLUTION: A shelf receiving column 28 mounted on an internal wall surface of a storage chamber includes a plate shaped column body set to a shorter size than a vertical internal size of the storage chamber, and a plurality of stopper holes are opened separately at a predetermined interval at the center of the body in a shorter direction in the same. Folded sections 28a folded at a predetermined angle toward the internal wall surface of the storage chamber are formed on opposite end edges in a shorter direction in the column body 30, i.e., opposite end edges located longitudinally of the column body 30. When the shelf receiving column 28 is mounted on the internal wall surface of the storage chamber, open ends of the both folded sections 28a, 28a make contact with each other so as to face the internal wall surface to prevent the open end from being exposed.
