Summary:In order to attach cup bearings 18 with good precision in portions between circular holes 15 that are formed in joining-arm sections 10 of yokes 7a, 7b of a cross shaft universal joint 6 and the tip-end sections of a shaft section 17a of a cross shaft 8 regardless of variation in the dimensions of the joining-arm sections 10, the circular holes 15 in the tip-end sections thereof, and the cup bearings 18, and elastic deformation of the joining-arm sections 10 of the yoke 7a during press-fitting work, press-fitting punches 33 are used to pressure fit the cup bearings 18 to a preset reference position inside the circular holes 15, and the value of the pressure that is applied to the press-fitting punches at that instant is set as a reference pressure, and at the instant when the pressure applied to the press-fitting punches becomes larger than the reference pressure by a preset specified value, the cup bearings 18 are determined to have reached positions where press-fitting is complete.
