クチエンジ式工具保持装置。 An arbor body having a through hole penetrating from one side in the axial direction to the other side, a tool body that is fitted into the through hole from one side of the arbor body, and a tool body that is fitted into the through hole from the other side of the arbor body and the tool body. A clamp rod whose one end is clamped in the through hole, a cap which closes the other side of the arbor body and is movably penetrated to the other end of the clamp rod, and a cap which is supported by the cap and urges the clamp rod toward the other end. The tool body is provided with an elastic body that tightens and fixes the tool body, and the clamp rod is moved against the elastic force of the elastic body by supplying pressurized fluid to the pressurizing chamber inside the through hole between the clamp rod and the cap. In a quick-change tool holding device that is biased toward one side to release the tightening of the tool body and rotate the tool body to attach and detach, the other side of the arbor body has a flat surface perpendicular to the central axis of the arbor body. A piston casing containing a piston slidably housed inside is attached, and one side of the piston that abuts against the other end of the clamp rod has a recess for accommodating the other end of the clamp rod when the tool body is in the tightened state. and a notch for abutting the other end of the clamp rod against the notch surface when the tool body is released, and the notch surface is located in the middle of the recess in the depth direction and in the recess in the sliding direction of the piston. A quick-change tool holding device characterized by a cutout parallel to the bottom surface of the tool.
