PURPOSE: To easily combine a yoke with a shaft by simple constitution. CONSTITUTION: A presser member 28 slidably fitted onto a shaft 7 is retracted towards the center of the shaft 7, when the end part of the shaft 7 is inserted into a yoke 3. After inserting, the presser member is displaced towards the end part of the shaft 7, so as to press against the bottom part of a base end part 8 of the yoke 3 by a presser plate part 30. |
