ることを特徴とするコレツトチヤツク。[Claims for Utility Model Registration] One end surface is fixed in contact with the main shaft, has a thread on the outer peripheral surface, and has a central hole on the inner periphery defined by an inner tapered surface whose inner diameter decreases toward the other end surface. a cylindrical chuck body; a stopper member that is fixed to one end surface of the chuck body or to the main shaft, faces the central hole, and has a stopper surface that abuts the workpiece; and a stopper member that is fitted into the inner tapered surface of the central hole. The collector has an outer tapered surface whose outer diameter decreases in a direction away from the main shaft, a shaft hole through which the work is inserted and grips the work with its inner circumferential surface, and a first engaging part, and is retractable in the radial direction. a collector sleeve, a female thread that engages with the male thread of the chuck body, and a second engaging part that engages with the first engaging part of the chuck body, and the male thread and the female thread are screwed together. A collector chuck comprising a nut member which, when brought together, moves the collector sleeve in a direction away from the main shaft and contracts the collector sleeve in the radial direction.
