Zusammenfassung:	A universal joint includes: a pair of yokes each including a pair of arms in each of which a bearing hole is formed; four bearings each including a bearing cup press-fitted into the bearing hole and a plurality of needle rollers; and a joint spider including four shafts respectively supported by the bearings. A clinched portion that hinders the bearing cup from slipping out of the bearing hole is formed at the peripheral edge of the bearing hole. In the universal joint, the clinching amount for forming the clinched portion is set in accordance with a radial clearance, which is formed between the shaft of the joint spider and the needle rollers, to adjust the size of the radial clearance.
