Abstract
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 space α and 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 space α and the outside, thus releasing out the air which has been sent into interior space α.
