Abstract
A structure of a resin-made pipe joint includes a joint body having a cylindrical shape, a sleeve having a cylindrical press-inserting portion which is press-insertable into the joint body and a cylindrical coupling portion which is press-insertable into a tube, and a fastening member for fixing the tube which is in a state where the coupling portion is press-inserted, to the joint body through the sleeve. The sleeve contains a sealing surface in an outer circumferential surface of the press-inserting portion, the sealing surface being closely contactable with an inner circumferential surface of the joint body, and comprises a non-contacting surface between the press-inserting portion and the coupling portion, the non-contacting surface forming a space with respect to the inner circumferential surface of the joint body, when the sealing surface is closely contacted with the inner circumferential surface of the joint body.
