PROBLEM TO BE SOLVED: To facilitate assembling ability of a cross member and a bearing cup assembly to a yoke opening. SOLUTION: Each leg part has an opening provided with a first bore formed to receive a bearing cup, and a second bore to which the end part of the bearing cup is extended. A pair of axially arrayed trunnions each having a bearing cup to be mounted are mounted on the opening in a manner to support a cross die between the leg parts of yokes. Thereafter, holding members are inserted in the second bores of respective openings, and the surface of one of the holding members is positioned at a bearing cup 48A. After the rotary shaft of a first shaft 12 is arrayed with the rotary shaft of a second shaft 14, the end parts of the leg parts for surrounding the second bores of respective openings are deformed in a manner so as to be engaged with one or more protrusion parts engaged with the surfaces, positioned opposed to each other, of the holding members and the holding members being fixed. |
