Claims

[Claims for Utility Model Registration] (1) An inner cylindrical portion having an annular convex portion on the outer circumferential surface of the connecting end of the tube and fitting into the inner circumferential surface of the tube, and an annular convex portion of the inner cylindrical portion. A joint body made of synthetic resin includes an outer cylinder part that concentrically surrounds the inner cylinder part on the inside in the axial direction and forms a tube insertion groove between the joint body and the outer cylinder part of the joint body. The fastener to be tightened is fitted into the inner cylinder part axially inside the annular convex part of the joint body, and the axially inner end surface intersects the end face of the outer cylinder part of the joint body and the inner peripheral surface. The fastener engages with the pressure receiving surface formed at the corner, and the axially outer end surface engages with the pressure surface formed on the inner surface of the fastener opposite to the end surface of the outer cylinder of the joint body. A pipe joint comprising a sleeve that presses a pipe inserted into a pipe insertion groove of a joint main body from the outer peripheral surface in the direction of the thickness of the pipe by tightening the sleeve. (2) The sleeve is an annular body with a triangular or polygonal cross section, with the inner circumferential side as the base and the base angles at both ends of the base as acute angles, and the pressure receiving surface of the outer cylinder of the joint body is The pipe fitting according to claim 1, wherein the pressure surface of the fastener is a tapered surface whose diameter decreases inward in the axial direction, and the pressure surface of the fastener is a tapered surface whose diameter increases in the direction of tightening the fitting body. . (3) The outer circumferential surface of the annular convex portion of the inner cylindrical portion of the joint body is formed with a tapered surface whose diameter increases axially inward from the end surface side and a cylindrical surface that is continuous with this tapered surface. The pipe joint according to claim 2, wherein a tapered surface whose diameter increases in the tightening direction is formed in a part of the inner circumferential surface of the joint body on the side facing the annular convex portion. (4) The pipe joint according to any one of claims 1 to 3, wherein the fastener and the sleeve are molded from synthetic resin.
