摘要： The assembly of a shaft member and a shaft end adapter which are manufactured separately can be accomplished with a high precision in coaxiality and straightness at a high efficiency. A tubular portion is formed with a circumferentially continuous portion at least in a part thereof adjoining a free end thereof, and a slit extends axially through a wall of the tubular portion in exclusion of the circumferentially continuous portion. A fastening bolt configured to close the slit is mounted on the tubular portion.
