Manufacturing method and manufacturing apparatus for universal joint

A manufacturing apparatus for a universal joint, the manufacturing apparatus comprising:

• a first shaft configured to press-fit a bearing, which supports a shaft portion of a joint spider such that the shaft portion is rotatable, to a first position in a through-hole of a yoke, to temporarily assemble the bearing with respect to the through-hole and the shaft portion;
• and
• a second shaft configured to clinch, after the bearing is temporarily assembled, a portion of the yoke around the through-hole, and press the bearing deeper into the through-hole with a clinched portion formed by the clinching, to press-fit the bearing to a second position located deeper than the first position in the through-hole.
