Claims

[Claims for Utility Model Registration] A tool that has a cylindrical shape and rotates around its axis, a fitting part that can be fitted to the rotating shaft at one end, and a processing tool at the other end. A tool holding member each having a holding portion, and a fitting portion of the tool holding member are fitted to the rotating shaft in a constant phase, and the tool holding member and the rotating shaft are in a state in which their contact surfaces are in contact with each other. detachment prevention means for preventing the tool holding member from detaching from the rotating shaft in a state where the tool holding member is relatively rotated by a predetermined angle; Relative rotation prevention means for preventing relative rotation of a member with respect to a rotating shaft; and a processing tool holding device comprising: a relative rotation preventing means for preventing relative rotation of a member with respect to a rotating shaft; forming a flange portion that protrudes radially outward and has an axial notch, and an extending portion that extends axially through the radially outer side of the flange portion;
an engaging part having a protrusion protruding radially inward from a distal end of the extending part; is rotated by the predetermined angle to form a shape that faces the engagement surface of the flange portion, and the ball is held in the protruding portion so as to be movable and engageable with the engagement surface of the flange portion; A processing tool holding device characterized in that a spring is provided to urge the ball toward an engagement surface, and the detachment prevention means is constituted by the flange portion, the engagement portion, the ball, and the spring.
