<p>PURPOSE: To obtain an air duct that disperses air uniformly by covering the outer surface of a pipe-shaped main body formed of an air permeable material with an air-impermeable and film-shaped material, and forming a linear slit through the film-shaped material and the main body. CONSTITUTION: A main body 1, which is formed by shaping an air permeable material into a pipe, blows air via its interior spaceαand also functions as a heat insulator. The entire outer surface of the main body 1 is covered with an air impermeable and film-shaped material 2 which is integrated with the outer surface of the main body 1 via an adhesive. A linear slit 3 formed through the film-shaped material 2 and the main body 1 opens and closes in response to the deformation of an air duct due to the difference in pressure between the interior spaceαand the outside, thus releasing out the air which has been sent into interior spaceα.</p> |
