Claims

[Claims for Utility Model Registration] A tool holding device that is attached to a rotating shaft of a machine tool, which is attached to the rotating shaft at one end, has a fitting hole extending in the axial direction at the other end, and has a tool holding device that is attached to the rotating shaft at one end, and has a fitting hole extending in the axial direction at the other end. a device main body having a first engaging portion at the bottom thereof; and a device body that is slidably but non-rotatably fitted in the axial direction to a portion of the fitting hole deeper than the first engaging portion, and is fitted with a spring to open the fitting hole. a drive member that is biased toward the side and has a non-circular first fitting portion at its tip; an operating member that slides the drive member against the biasing force of the spring; and a tool at one end. having a holding part, and having a second fitting part fitted to the first fitting part in a relatively non-rotatable manner at the other end;
and a second engaging part that can be engaged with and disengaged from the first engaging part in the axial direction at a specific relative phase, and that cannot be disengaged by being rotated by a certain angle after engagement. A tool holding device capable of being quickly replaced, comprising: a tool holding shaft fitted into a main body.
