ABSTRACT:
A shaft body has an engagement portion with a slip-off preventing groove, and a positioning recess extending from the engagement portion. A shaft joint having an engagement groove to be engaged with the engagement portion and a bore facing the engagement groove is provided with a flexible member which is provided on an outer side in a longitudinal direction of the engagement groove to be engaged with the positioning recess. When an insufficient amount of engagement prevents engagement in the correct position, the engagement portion contacts with the flexible member and prevents the shaft body from engaging with the shaft joint. When canceling the coupling for maintenance, etc., the engagement of the flexible member with the positioning recess is cancelled by deflecting the flexible member in a width direction of the engagement groove. Consequently, the shaft body can be easily pulled out in a longitudinal direction of the engagement groove.
