Claims

[Claims for Utility Model Registration] A cylindrical screw member with unevenness on its outer peripheral surface is held so as not to rotate relative to each other, and the screw member is rotated by a drive motor to be tightened in a predetermined manner. A work holder for a tightening device that is screwed onto a mounting member, the workpiece holder being driven to rotate around an axis by the drive motor, and having an accommodation hole provided in the axis to concentrically accommodate the screw member. , and a holder main body having a through hole formed in the peripheral wall of the accommodation hole substantially perpendicular to the axis, and having a dimension larger than the thickness of the peripheral wall and movably disposed within the through hole. an engaging piece slidably disposed on the outside of the holder main body,
The sliding member is characterized by having a sliding member that is engaged with the engagement piece to push the engagement piece into the accommodation hole and engage with the unevenness of the screw member inserted into the accommodation hole. Work holder for tightening device.
