ルダ。 The holder body rotates integrally with the rotating spindle of the machine tool, and one end is inserted and supported in the shaft hole of the holder body so that it can rotate integrally and move in the axial direction, and the other end has a tap adapter. a tap spindle provided with a male thread and a flange portion formed in the intermediate portion; and a tap spindle provided around the holder main body and the tap spindle so as to be relatively rotatable and locked to a stationary part of the machine tool to restrict rotation. a casing, a master screw formed with a female thread that engages with the male screw to restrict axial movement and rotation only in one direction; and a master screw provided within the casing when the tap spindle rotates forward. a clutch that engages with the master screw to restrict rotation of the master screw; a spring that is elastically deformed when the tap spindle rotates forward and the flange portion abuts the forward movement stop portion; The invention is characterized by comprising a ratchet device that restricts the rotation of the master screw when the tap spindle rotates forward, and allows rotation of the master screw when the tap spindle rotates backward and the clutch is disengaged. Tapping holder.
