PURPOSE: To provide a refrigerating and cooling cabinet which has a simple constitution and in which the volume of cold air sent to a plurality of cooling chambers are controlled independently and respectively.

CONSTITUTION: In a refrigerating and cooling cabinet 1a shielding plate 9 of one body is provided between air delivery ports 5,6,7 for a plurality of cooling chambers 2, 3, 4, respectively, and a guide channel 28 for sending cold air from a delivery air fan 14. When the shielding plate 9 is moved by a stepping motor 13, a combination of opening and closing of the air delivery ports 5, 6, 7 is determined by the position of stopping of an air passage port in the shielding plate 9. With this arrangement it is possible to realize the function to open and close the air delivery ports 5, 6, 7 to the cooling chambers 2, 3, 4 independently. This function can be realized by a simple constitution which consists of the wall plate 8 and shielding plate 9 that are two plate shaped bodies, the air delivery ports 5-7 of the wall plate 8, and the relative arrangement of the shielding plate 9 and the air passage port.
