を特徴とするチヤツク。 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. A rotary cylinder having a tapered inner circumferential surface and a roller holding cylinder having a group of roller holding holes 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 chuck is designed to cause a large number of needle rollers to rotate spirally around their own axis by rotating in the forward and reverse directions, thereby shrinking the chuck tube or restoring the shrinkage. Consists of multiple roller holding holes and single roller holding holes arranged alternately in the direction around the axis of the cylinder, and each double roller holding hole and each single roller holding hole has a plurality of needle rollers and one needle roller, respectively. A chuck characterized by holding.
