Abstract
In a yoke for a cross shaft universal joint, the circumferential phases of the arrangement direction X of a pair of connecting arm parts and the arrangement direction Y of first and second flange parts are shifted from each other. A bolt is tightened to put the first and second flange parts nearer to each other, thereby applying mutually approaching forces to the connecting arm parts in directions inclined relative to the axes of circular holes. Thus, cup bearings incorporated in the circular holes are pressed against the end of a shaft part constituting a cross shaft, thereby enabling suppression of occurrence of shaking motion between the bearings incorporated in the circular holes and the end of the shaft part of the cross shaft rotatably supported by the bearings.
