管の継手構造。 A joint structure for connecting a stainless steel pipe to a joint body includes a sealing member, a retaining ring, and a nut member, a female thread is formed on the inner peripheral surface of the joint body, and the female thread is screwed into the nut member. While forming a male threaded portion, one tapered pressing surface is formed on the tip edge of the male threaded portion of the nut member, and another tapered pressing surface is formed on the opposing inner peripheral surface of the joint body, so that both taper pressing surfaces are formed. A stainless steel pipe characterized in that the retaining ring is pressed between the faces in the centripetal direction of the stainless steel pipe, and a mounting groove for mounting the seal member is formed independently on the inner peripheral surface of the joint body. Joint structure.
