PROBLEM TO BE SOLVED: To provide a universal joint to lengthen the lifetime of a bearing. SOLUTION: A rolling element 39 held in a bearing hole 4 of a split yoke 3 is fitted into an inner ring 41 of a shaft section 1a, and a bottom plate 38 sandwiched between a first thrust receiving plate 36 and a second thrust receiving plate 40 is fitted between the shaft section 1a and the bottom of the bearing hole 4, so that the bottom side inner peripheral edge of an outer ring 37 is inserted in the bottom of the bearing hole 4 with the outer peripheral edge of the bottom plate 38, and the outer ring 37 is secured in the bearing hole 4. A securing means of the outer ring 37 to an arm section 3c is installed between the shaft section 1a of a cross shaft 1 and the bottom of the bearing hole 4. Without the need for providing a space of the securing means in the shaft section 1a of the cross shaft 1 which is constant in the centerline direction length, the residue of the shaft section 1a becomes longer by the space one, and the bearing 35 inserted between the shaft section 1a of the cross shaft 1 and the arm section 3c of the split yoke 3 widens so that the load applied on the bearing 35 relatively lessens so as to lengthen the lifetime of the bearing 35.
