PROBLEM TO BE SOLVED: To inexpensively realize a structure whereby a shaft and a yoke can be fixedly connected while performing alignment of these shaft and yoke, based on tightening of a retaining bolt. SOLUTION: In a retaining bolt 15a, an elliptic cylindrical cam member 20 is elastically externally fitted. When the retaining bolt 15a is screwed to a screw hole 12, a peripheral surface of this cam member 20 presses an outer surface of a shaft 7, alignment of this shaft 7 to a yoke 3 is performed. When the retaining bolt 15a is tightened, this retaining bolt 15a is rotated inside the cam member 20. |
