Abstract
In a coupling structure for coupling a shaft to a universal joint yoke, an insertion portion of a shaft is passed through an insertion hole of a universal joint yoke. An outward protrusion of a distal end portion of the shaft faces a peripheral edge of a first opening of the insertion hole across a gap in an axial direction. A fixed portion that adjoins the insertion portion is fixed to a peripheral edge of a second opening of the insertion hole by welding. An engaging portion formed on an outer periphery of the insertion portion and an engaged portion formed in an inner periphery of the universal joint yoke, which defines the insertion hole, are engageable with each other in a rotational direction with a rotation permitting gap for phase adjustment.
