Abstract

PURPOSE: To obtain an air duct which can disperse air uniformly by covering the inner surface of a main body, which is made by shaping a material comprising communicating textures into a pipe, with an air impermeable and film- shaped material, and forming a linear slit including at least the film-shaped material. 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 for reducing the heat loss between the interior space α and the outside. The entire inner surface of the main body 1 is covered with an air impermeable and film-shaped material 2. The film-shaped material 2 is air impermeable and is integrated with the main body 1 via an adhesive. A linear slit 3 formed to include the film-shaped material 2 opens and closes in response to the deformation of an air duct A due to the difference in pressure between the interior space α and the outside, thus releasing out the air which has been sent into the interior space α.
