On the other hand, in a flexible duct of an air conditioner, there is a bellows-shaped hose (hereinafter referred to as a bellows hose). However, since the bellows hose is bent into a W shape, the diameter of the bent portion is small. There is a problem that the diameter of the hose becomes large and bulky when the hose is enlarged and contracted. Also, since it is a hard hose made of plastic, it becomes a rigid cylinder with a cylindrical shape when it is contracted, and it is difficult to wind and store it. Good but
