Claims (1)

[Claims for Utility Model Registration] (1) On one side edge, there is a fitting part that is bifurcated and has a retaining part provided oppositely on the inner edge of the opening end, and on the other side edge, it has a fitting part that slides into the fitting part. A band-shaped synthetic resin profile having a locking part that can be fitted and locked is spirally wound, and in the wound state, the fitting part and the locking part that are adjacent to each other are fitted. A connection structure between a helical tube formed into a cylindrical shape and having elasticity and flexibility, and a cylindrical joint member connected to an end of the helical tube, wherein the helical tube is connected to an outer periphery of the tube. At least one rib is provided on the outer wall surface of the fitting portion, which is a surface, protruding along the longitudinal direction of the profile, and one of the open end surfaces of the fitting portion is located on the outer peripheral side of the tube. A waterproof material having elasticity is provided over the entire length of the profile on at least one of the opening end surface of the pipe and the outer surface of the shoulder part that comes into contact with the opening end surface of the adjacent fitting part when the pipe retracts. On the other hand, the coupling member has a connecting portion into which an end of the spiral tube is inserted, and a spiral groove is formed on the inner circumferential surface of the connecting portion to be screwed into the rib. teeth,
The pitch at at least one location is made approximately equal to the spacing between the ribs when the helical tube is retracted, and by screwing the connecting portion of the joint member and the helical tube together, a spiral is formed within the connecting portion. A connection structure between a helical tube and a joint member, characterized in that the two are connected and fixed in a state where at least one portion of the tube is retracted. (2) It has a fitting part on one side edge that is bifurcated and has a retaining part on the inner edge of the opening end, and has a locking part on the other side that is slidably inserted and locked into the fitting part. A telescoping device in which a band-shaped synthetic resin profile having a stop part is spirally wound, and the fitting part and the stop part, which are adjacent to each other in the wound state, are fitted to form a cylindrical shape. A connection structure between a helical tube having elasticity and flexibility and a cylindrical joint member connected to an end of the helical tube, wherein the helical tube is connected to the fitting portion, which is the outer circumferential surface of the tube. At least one rib is provided on the outer wall surface to protrude along the longitudinal direction of the profile, and the joint member has a connecting part into which an end of the spiral pipe is inserted, and the inner part of the connecting part is inserted. A spiral groove is formed on the circumferential surface to engage with the rib, and the groove includes:
The pitch at at least one location is made approximately equal to the spacing between the ribs when the helical tube is retracted, and by screwing the connecting portion of the joint member and the helical tube together, a spiral is formed within the connecting portion. At least one portion of the tube is retracted, and at the retracted portion, between the opening end surface of the fitting portion that is located on the outer peripheral side of the tube and the outer surface of the shoulder that abuts the opening end surface. 1. A connection structure between a helical tube and a joint member, characterized in that the two are connected and fixed in a state in which a water stop material having elasticity is compressed and held.
