Abstract

PURPOSE: To provide an air duct which can uniformly release the air by covering an impermeable film on the outer surface of a main body made of permeable materials and formed in a pipe shape, and arranging a dotted line in the film. CONSTITUTION: A main body 1 is formed in a pipe shape and is made of permeable materials, and it functions as a heat insulator while an air is ventilated into the inner space. An impermeable film 2 is covered on the whole outer surface of the main body 1. The film 2 is impermeable and a dotted line 3 is formed in it. At least one end of the film 2 closer to the dotted line 3 is not adhered to the main body 1 and becomes a free end 4. This free end 4 functions as a valve to release the air of the area into the outer space.
