PROBLEM TO BE SOLVED: To provide a yoke of a Cardan joint realizing increase of a joint angle while miniaturizing, lightening and reducing cost of it. SOLUTION: A yoke 1 is a punched and pressed molding with a metal sheet as a material and has a base part 13 welded and connected to a first steering shaft 9 and a pair of arms 15 provided extensionally from this base part 13. A columnar fitting part 17 to fit into the first steering shaft 9 is projectively provided on the base part 13, and a surface pressing part 21 concentric with a joint center O and making concave spherical surface of a radius R is formed on a ridge line part between the both arms 15. The radius R of the surface pressing part 21 is set slightly larger than a turning radius R' of a yoke 3 on the mating side with the joint center O as a center of oscillation.
