A joint unit comprises a lock mechanism in which a ball-like joint section provided at the base end of an arm is housed in a holder formed at an end of a cylindrical case. As the joint section is brought into pressed contact against an inner surface of the holder, the lock mechanism locks a pivotal angle. In the lock mechanism, in response to a manual operation of a knob, a bolt is caused to project into the case and this pressing force is transmitted to a roller-like first pressing body and then to a second pressing body placed in contact therewith. Further, the pressing force from the first pressing body is transmitted to a pressure block and then the pressing force from this pressure block brings the joint section into pressed contact against the holder inner surface.

It is an object of the invention to provide a tap holder in which even when an error is brought about in synchronizing spindle feeding and rotation of a tapper body and a tap collet of a tap holder in correspondence with a machine tool spindle, the synchronization can be established by absorbing the error by a simple constitution. As means therefor, the tap holder is characterized in that a tapper body and a tap collet are inserted by a locking member at portions of the tapper body and the tap collet overlapping each other, and the tap collet is fixed to the tapper body by engaging the locking member with at least one of the tap collet and the tapper body in a state of being interposed with an elastic member on both sides thereof in an axial direction X.
