<p>PROBLEM TO BE SOLVED: To obtain a joint construction with an improved watertightness by connecting together a ribbed tube and an attaching tube with a flexible joint main body. SOLUTION: In a joint construction 1, a joint 4 is equipped with a flexible joint joint main body 6, a pushing cover 7 and a receiving cover 8. The joint main body 6 has a cylindrical portion 6a and a saddle portion 6b, and the saddle portion 6b is overhung on the ring-shaped rib 2a. At the inner side of the saddle portion, an upper side water stop layer 9 is provided. The pushing cover 7 has a through-hole 7a, and a covered portion 8a by the saddle portion 6b is provided. Both the pushing cover 7 and receiving cover 8 are tightened in the tube peripheral direction of the ribbed tube 2. A cylindrical portion 6a is tightly adhered to the vicinity of the connecting end 3a of the attaching tube 3. The receiving cover 8 covers a ring-shaped rib 2b at the lower side, and the lower side water stop layer 10 is tightly adhered to the ring-shaped rib 2b. The pushing cover 7 tightly adheres the saddle portion 6b to the covered portion 8a.</p> |
