Claims

[Claims for Utility Model Registration] 1. A sliding socket is inserted movably in the axial direction into a joint pipe in which an outer cylinder and a lid cylinder are combined, and the outer cylinder is the same as the synthetic resin pipe to which it is connected. It is made of synthetic resin material, has a socket inside the tip for connecting one synthetic resin pipe, a male thread on the outer circumferential surface of the rear end, and the inside from approximately the center to the rear end is connected to the sliding socket. The sliding socket is made of the same synthetic resin material as the synthetic resin pipe to be connected, and has a circumferential groove on the outer circumferential surface near the center or tip. An annular elastic body is fitted into the circumferential groove to make sliding contact with the inner circumferential surface of the outer cylinder, and a socket for connecting the other synthetic resin pipe is formed inside the sliding socket from approximately the center to the rear end. The lid cylinder has a female thread formed on the inner peripheral surface of the tip that engages with a male thread formed on the outer cylinder, and an inner cylinder with a diameter that allows the sliding socket to be inserted movably in the axial direction. 1. An expansion joint characterized by having a small diameter stopper part formed inside the rear end. 2. The expansion joint according to claim 1, wherein the outer peripheral surface of the distal end of the sliding socket is formed into a spherical shape. 3. The expansion joint according to claim 1 or 2 of the utility model registration claim, wherein a sharpened portion is formed on the outer circumferential surface of the annular elastic body that is fitted into the circumferential groove of the sliding socket. 4. A utility model registered as claimed in any one of claims 1 to 3, characterized in that grooves are formed in the circumferential direction on the side surface of the annular elastic body that is fitted into the circumferential groove of the sliding socket. expansion joint.
