PROBLEM TO BE SOLVED: To provide a universal pipe joint capable of preventing formation of a recessed part, in which water and dirt reside, in a connection part while capable of adjusting connection angle similarly with a conventional universal joint. SOLUTION: This universal joint 11 has a spherical receiver opening member 14 provided with a spherical inner surface part 19 having diameter larger than that of a tube body 18 in an end of the tube body 18, a connecting cylinder 15 inserted into the tube body of the spherical receiver opening member and having a tip projecting inside the spherical inner surface part, and a spherical outer surface part 20 corresponding to the spherical inner surface part of the spherical receiver opening member, and this universal joint 11 is provided with a turning cylinder 17 having a flow-in tube insert part, into which a flow-in tube 16 is to be inserted. An axis 17C of the flow-in tube insert part is displaced from an axis 15C of the connecting cylinder, and an opening edge of the tip of the connecting cylinder is inclined so that a lower part is projected in a direction of the flow-in tube, and both side surface parts thereof are formed larger than the outer diameter of the flow-in tube.
