A cylindrical spline shaft is coaxially connected to the main shaft via a holder, a slit is formed in a part of the spline shaft in the axial direction and a part in the circumferential direction, and the movable piece is inserted into the slit in the circumferential direction. A drive rod having a large diameter flange is used in a machine tool chuck which is fitted so as to be slightly rotatable and has a pawl having the same diameter and approximately the same tooth shape as the pitch circle of the spline shaft teeth on the outer surface of the movable piece. is screwed to the axial center of the holder so as to be movable and rotatable in the axial direction, and a member facing both axial end surfaces of the flange is provided with a regulating pin that can be adjusted forward and backward toward the end surface of the flange. A claw regulating device for a chuck for a machine tool, characterized in that one end of the movable piece is connected to the movable piece so as to be non-rotatable and movable in the axial direction.
