Zusammenfassung:	To provide an inner ring which can inhibit an axial outer end part of an expansion part from falling to the radial inner side, and to provide a pipe joint.SOLUTION: An inner ring 4 of a pipe joint 1 includes an expansion part 6 which is formed protruding to the radial outer side at an axial outer end part and press-fitted in a tip part of a tube 8. A fluid passage 4a is formed at the radial inner side of the expansion part 6. The expansion part 6 is formed so as to be tapered from the axial inner side to the axial outer side in an axial cross sectional view and has a flat surface 6e formed at an axial outer end and extending in a radial direction.SELECTED DRAWING: Figure 3 【課題】膨出部の軸方向外端部が径内側へ倒れ込むのを抑制することができるインナーリング及び管継手を提供する。【解決手段】管継手１のインナーリング４は、軸方向外端部において径外側に突出して形成され、チューブ８の先端部内に圧入される膨出部６を備え、膨出部６の径内側に流体流路４ａが形成されている。膨出部６は、軸方向の断面視において、軸方向内側から軸方向外端へ向かって先細るように形成されており、軸方向外端に形成された径方向に延びる平坦面６ｅを有する。【選択図】図３
