Zusammenfassung:To provide a universal joint which is excellent in durability.SOLUTION: A universal joint 1 comprises: a joint cross 2; bearings 3 arranged at shafts of the joint cross; a pair of yokes 4, 5 connected to each other via the joint cross and the bearings so as to be turnable; and bearing caps 6 for covering the bearings. Shot peening is applied to each joining face between the yokes and the bearing caps. Double-shot peening may be applied to each joining face between the yokes and the bearing caps. Each joining face between the yokes and the bearing caps may be formed into an engaged saw-tooth shape in which a crest and a trough are alternately continued in a direction perpendicular to an axial line direction of the shaft which is gripped by the yokes and the bearing caps.SELECTED DRAWING: Figure 1 【課題】耐久性に優れる自在継手を提供する。【解決手段】十字軸2と、十字軸の各軸に設けられる軸受3と、十字軸及び軸受を介して互いに回動自在に結合される一対のヨーク4、5と、各々の軸受を覆うベアリングキャップ6とを備え、ヨークとベアリングキャップとの接合面の各々に、ショットピーニング加工が施されている自在継手1。ヨークとベアリングキャップとの接合面の各々にダブルショットピーニング加工を施してもよい。ヨークとベアリングキャップの接合面の各々を、ヨークとベアリングキャップとで把持される軸の軸線方向に対して垂直な方向に山と谷が交互に連続し、互いに噛み合う鋸歯状に形成してもよい。【選択図】図1
