Claims

[Scope of utility model registration request]

In the tension ring used for modifying the gripping part of the chuck jaw, two pins can be slid in the radial direction of the tension ring at positions corresponding to the S symmetry point at the center of both ends of the gripping part of each chuck jaw. inserting the pin into the center of the tension ring, and screwing a shaft having a tapered surface that can be adjusted in the axial direction into the center of the tension ring, and biasing each of the inner ends of the pins by a preload spring so as to be in constant pressure contact with the tapered surface.
A variable tension ring characterized in that the outer end of each pin (two pins) is placed against a chuck claw gripping part to obtain one tension.
