Claims

[Scope of utility model registration request]

The rotating barrel is equipped with a chuck barrel for gripping a tool, and a rotary barrel that fits onto the outer circumferential surface of the chuck barrel via a rolling element. In a tool holding device, the chuck tube is moved relative to the chuck tube in the axial direction by the rotation of the chuck tube, thereby reducing or expanding the diameter of the chuck tube. An annular side plate is fitted so as to be immovable in the direction, and this side plate has an outer diameter that tightly contacts the inner peripheral surface of the rotating cylinder when the chuck cylinder is tightened, and when the chuck cylinder is tightened, it bends and contracts the tip of the chuck cylinder. A tool holding device characterized by having a rigidity that allows the diameter to be increased.
