Claims

[Scope of utility model registration request]

One pipe having an outwardly projecting protrusion at its end, the other pipe having an arc-shaped bulge at its tip, an intermediate pipe, and the above pipe extending from one end surface of the intermediate pipe toward the inner periphery of the intermediate pipe. an enlarged diameter section provided so that the bulge fits therein; a cylindrical packing interposed between the enlarged diameter section and the bulge;
a nut that is fitted on the outer peripheral pipe side of the bulge and is screwed onto one end of the intermediate pipe to push the bulge into the enlarged diameter portion;
A stepped portion is provided so that the protrusion fits inward from the other end of the inner circumference of the intermediate pipe, an enlarged diameter stepped portion provided inward from the open end of the inner circumference of this stepped portion, and screwed into this enlarged diameter stepped portion. A retaining ring on the protrusion, a packing interposed between this ring and the enlarged-diameter step, a nut fitted onto one pipe and screwed onto the other end of the intermediate pipe, and a ring extending from the outer end surface of the ring toward the inner circumference. A joint consisting of a tapered part, a ring fitted on one pipe and a tapered ring so as to be pushed into the tapered part by tightening a nut.
