PROBLEM TO BE SOLVED: To obtain an assembling method of a universal joint which can accurately assemble cup bearings into portions between circular holes constituting yokes and tips of shaft parts constituting a joint cross irrespective of a variation of dimensions of constituent members.SOLUTION: A cup bearing 18 is pressure-inserted into a preset reference position at the inside of a circular hole 15 by using a pressure-insertion punch 31 constituting a pressure-insertion caulking device 29, and a value of pressure applied on the pressure-insertion punch 31 at that point of time is stored as a reference pressure. Then, the cup bearing 18 is further pressure-inserted from the reference position, and when the pressure applied to the pressure-insertion punch 31 becomes higher than the reference pressure by a preset prescribed value, it is determined that the cup bearing 18 reaches a pressure-insertion finish position, and pressure-insertion work is finished. |
