PROBLEM TO BE SOLVED: To provide a universal joint yoke capable of suppressing interference against a mating-side yoke even at a large bending angle.SOLUTION: A first yoke 51 includes a cylindrical portion 60 extending in a first direction Z1 (axial direction), a flange 64, and a pair of arms 65 extending from the flange 64. A joint cross support hole 68 is formed in a tip end 65b of the arm 65. The pair of the arm 65 has an inner side surface 66 facing each other in a second direction Z2. The inner side surface 66 includes a first recess 81 and a second recess 82 as viewed from a third direction Z3 orthogonal to the first direction Z1 and the second direction Z2. The first recess 81 enlarges a gap between the inner side surfaces 66 of the pair of the arms 65 as going from a starting end 81S on an opening edge 70a side of the support hole 68 toward a terminal end 81E on a base end 65a side of the arm 65. The second recess 82 connects the terminal end 81E and an end surface 64a of the flange 64 in a round shape.SELECTED DRAWING: Figure 4

    【課題】大きな折れ角においても相手側ヨークに対する干渉を抑制できる自在継手ヨークを提供する。【解決手段】第1ヨーク51が、第1方向Z1(軸方向)に延びる筒状部60と、フランジ64と、フランジ64から延びる一対のアーム65とを含む。アーム65の先端部65bに十字軸用の支持孔68が形成される。アーム65は、第2方向Z2に対向する内側面66を含む。第1方向Z1及び第2方向Z2と直交する第3方向Z3から見て、内側面66が、第1逃げ部81と第2逃げ部82とを含む。第1逃げ部81は、支持孔68の開口縁部70a側の始端81Sからアーム65の基端部65a側の終端81Eに向かうにしたがって一対のアーム65の内側面66間の間隔を拡大させる。第2逃げ部82は、終端81Eとフランジ64の端面64aとをR状に接続する。【選択図】図4
