Summary:To provide a constant velocity universal joint which unfailingly prevents pressure rise at its interior during assembly, and to provide an assembly method of the constant velocity universal joint.SOLUTION: A constant velocity universal joint 7 includes: an outer ring member 8 including grooves 8e extending in a rotation axis direction on its inner peripheral surface; a power transmission member 10 which rolls or slides on the groove 8e; a sealing member 9 which is fitted on the outer ring member 8; and a shaft member 14 on which the sealing member 9 and the power transmission member 10 are fitted. The shaft member 14 includes: a small diameter part 14a which is located at a first end part in the rotation axis direction and on which the power transmission member 10 is fitted; a large diameter part 14e having an outer diameter larger than that of the small diameter part; a fitting groove 14b which is provided between the small diameter part 14a and the large diameter part 14e and on which the sealing member 9 is fitted; and a temporary part 14d provided adjacent to the fitting groove 14b in the rotation axis direction. The groove 14c extending in the rotation axis direction is formed on an outer peripheral surface of the temporary part 14d.SELECTED DRAWING: Figure 2 【課題】組立時に内部の圧力上昇を確実に防止する等速自在継手、及びその組立方法を提供する。【解決手段】回転軸方向に延在する複数の溝８ｅを内周面に備える外輪部材８と、溝８ｅを転動または摺動する動力伝達部材１０と、外輪部材８に外嵌される封止部材９と、封止部材９及び動力伝達部材１０が外嵌される軸部材１４を備え、軸部材１４は、回転軸方向の第１端部に動力伝達部材１０が外嵌される小径部１４ａと、小径部よりも外径が大きい大径部１４ｅと、小径部１４ａと大径部１４ｅとの間に備えられ、封止部材９が外嵌される嵌合溝１４ｂと、回転軸方向に、嵌合溝１４ｂに隣接して設けられる仮設部１４ｄと、を備え、回転軸方向に延在する溝１４ｃが仮設部１４ｄの外周面に形成されている等速自在継手７。【選択図】図２
