To improve reliability and durability of a cross shaft universal joint incorporating a cross shaft 9 by achieving a structure of making shaft parts 14, 14 of the cross shaft 9 hardly come off from circular holes 12, 12 of the joint arm parts 11a, 11a of a yoke 8c.
Bent parts 28, 28 are provided by bending inward in the radial direction both ends in the circumferential direction of portions, where circular holes 12, 12 are each formed, of a pair of joint arm parts 11a, 11a of a yoke 8c. Thereby, among both the joint arm parts 11a, 11a, inside surfaces of both ends in the circumferential direction of portions where the circular holes 12, 12 are formed with respect to the axial direction are projected similarly inward in the radial direction from the inside surfaces of the intermediate portions in the circumferential direction.
