Claims

[Claims for Utility Model Registration] It is approximately cylindrical, has a joint part at one end for joining with other piping, and has a small diameter part, a medium diameter part, and a large diameter male thread on the outer peripheral surface of the other end. in this order,
A joint body has a stepped part between them, and one end has a female thread that engages with the large-diameter male thread of the joint body, and the inner peripheral surface of the other end has a tapered surface that narrows outward and the outermost end. A cap nut having a flange at the bottom; a substantially cylindrical rubber gasket having a tapered outer circumferential surface along the tapered inner circumferential surface of the cap nut and having a snap spring integrally fixed to the small diameter end of the outer circumferential surface; A joint for a corrugated pipe, comprising a rubber seal, a coil spring provided between the large diameter side of the outer circumferential surface, the side surface, the medium diameter part of the joint body, and the stepped part between the large diameter male thread part.
