Claims

[Claims for Utility Model Registration] A joint body in which a male thread and a tapered surface are provided on the outer and inner walls of the cylindrical end through which the pipe member is inserted, respectively, and a female thread that is screwed into the male thread of the joint body. A nut having one end formed with an annular flange portion through which the pipe member is inserted, the other end having an inclined surface formed inside the annular flange portion, and a tongue portion formed so as to be able to abut on the inclined surface of the nut. a washer into which the pipe member is inserted; and an elastic seal member having a through hole into which the pipe member is inserted and an outer surface formed with a tapered portion that abuts the tapered surface of the joint body, and is directed toward the joint body. A pipe joint characterized in that the movement of the nut presses an elastic seal member between a pipe member and a joint body, and the nut is positioned by bending a tongue portion by an inclined surface of the nut.
