PROBLEM TO BE SOLVED: To provide a structure at a low price which aligns a shaft and a yoke based on tightness of a bolt and combines and fixes the shaft and the yoke. SOLUTION: A presser cylinder 19 comprising and external cylinder 23 and an elastic material 25 is fitted out to a presser bolt 15. The presser bolt 15 is screwed to a screw hole 12 so that an outer diameter of the presser cylinder 19 spreads and an peripheral face of the presser cylinder 19 pushes a outer face of a shaft 7 so as to align the shaft 7 and a yoke 3. Therefore, although it is simple structure, troublesome work is not required, while a shaft is aligned, resulting in providing a universal joint with good assembling property. |
