ラを保持したことを特徴とするチャック。A chuck tube having a tapered outer circumferential surface provided at the tip of the chuck body, and a tapered tube corresponding to the taper of the outer circumferential surface of the chuck tube that engages with the outer circumferential surface of the chuck tube via a number of needle rollers. It is equipped with a rotating cylinder having a tapered inner circumferential surface, and a roller holding cylinder having a large group of rollers for arranging a large number of needle rollers so as to be inclined with respect to the axes of the chuck cylinder and the rotating cylinder. This is a chuck in which a large number of needle rollers are not rotated on their own axis but revolved by screwing in the opposite direction, thereby shrinking the chuck tube or restoring the shrinkage. It is composed of a group of multiple roller holding holes and a group of single roller holding holes arranged alternately in both the direction and the axial direction, and each of the multiple roller holding hole and single roller holding hole has 711 needle rollers and one needle. A chuck characterized by holding a roller.
