Abstract
After a cup bearing () is incorporated into a circular hole () of a coupling arm portion () forming a yoke, a notch () having a V-shaped cross section is formed in a portion near the periphery of the circular hole () on an outer side surface of the coupling arm portion (). Thereafter, a thin-walled portion () having a substantially trapezoidal cross section formed in a radially inner portion of the notch () in an opening edge portion of the circular hole () is plastically deformed inward in a radial direction to form a staking portion (). Therefore, it is possible to achieve a method of assembling a joint cross type universal joint and a joint cross type universal joint which can form the staking portion for preventing the cup bearing from falling off without complicating the staking work.
