That is, when assembling a product, it is necessary to correctly adhere the seal member to a fixed position with an adhesive, and to disassemble the product, it is necessary to peel off the seal member attached with the adhesive. In order to recycle the product, it is necessary to remove the sealing member and then wash the adhered adhesive. Further, when peeled, the seal member such as urethane is easily broken, and it is difficult to reuse the seal member as it is. Further, since the sealing member and the duct to which it is attached are generally made of different materials, they are not suitable for material recycling.

In the case of joining, as shown in FIG. 1 (a), from the state where the first duct 1 and the second duct 2 are separated from each other, the two ducts are gradually brought closer to each other, and the first and second corrugated portions 3a and 3b are formed. Touch each other. Further, when the two ducts are slightly approached from this state, the diameter of the second wavy portion 3b becomes larger than the diameter of the first wavy portion 3a.
Is slightly smaller, the first and second corrugated portions 3a and 3b are elastically deformed, and the first duct 1 and the second duct 2 are joined as shown in FIG. 1 (b). State. In this joined state, the first and second corrugated portions 3a and 3b are urged by their elastic force, and the two ducts can be joined without leaking the air flowing inside the two ducts. On the contrary, when the two ducts are separated from each other, the separation can be easily performed by gradually separating the two ducts.
