る機構とから成るタツプホルダ。 a holder body having a shank portion at one end and a cylindrical portion at the other end; a sleeve inserted into the holder body so as to be movable in the axial direction and relatively rotatable in the circumferential direction; A driven shaft for holding the tap is inserted so as to be slidable in the axial direction and relatively rotatable in the circumferential direction, a sizing clutch mechanism that connects the sleeve and the driven shaft, and a clutch mechanism for connecting the holder body and the driven shaft. A misalignment compensation mechanism is provided between the rear ends to absorb misalignment due to the difference between the reverse rotation of the main shaft of the machine and the rise of the backward motion, and the driven shaft stops after threading, enters the return motion, and retreats from reverse rotation. When the operation starts up faster, the holder body and the sleeve are moved relative to each other in the pulling direction, so as to release the lock between the holder body and the sleeve and prevent the positional relationship between the clutch and the clutch pin from changing. A tap holder consisting of.
