続構造。[Claims for Utility Model Registration] One side edge has a fitting part that is bifurcated and has a retaining part opposite to the inner edge of the opening end, and the other side edge has a fitting part that is slidably fitted into the fitting part. A band-shaped synthetic resin profile having a locking portion is wound spirally, and in the wound state, the fitting portion and the locking portion that are adjacent to each other are fitted to form a cylindrical shape. A connection structure between a spiral tube having stretchability and flexibility and a cylindrical joint member connected to an end of the spiral tube, the spiral tube forming an outer peripheral surface of the tube. At least one rib is provided on the outer wall surface of the fitting part to protrude along the longitudinal direction of the profile, and the joint member has a connecting part into which an end of the helical tube is inserted; A spiral groove is formed on the inner circumferential surface of the connecting portion, and the groove screws into the rib.
The pitch is approximately equal to or slightly larger than the spacing between the ribs when the helical tube retracts, and the connecting portion of the joint member and the helical tube are screwed together, and A bonding agent is filled in the gap between the fitting parts that occurs on the outer circumferential surface of the helical tube in the connection part, and in the gap between the helical tube and the connection part, so that the end of the helical tube is connected and fixed within the connection part of the coupling member. A connection structure between a helical tube and a joint member, characterized by:
