゛The sleeve part of the chuck body has a tapered outer circumferential surface of a tool fitting sleeve part integrally formed with the shank part, and a tightening device having an inner circumferential surface formed in a tapered shape corresponding to the tapered outer circumferential surface of this sleeve part. This is a roll lock milling chuck in which a nut is tightened in an externally fitted manner through a group of needle rollers, and this sleeve part is elastically deformed to reduce its diameter and grip the shank part of a tool fitted inside. In this step, slit-shaped cut portions that open toward the tool fitting hole are formed on the peripheral wall of the sleeve portion from the end surface thereof along the axis of the sleeve portion and at equal angles in the circumferential direction. A roll lock milling chuck characterized by having the inner peripheral part of the peripheral wall divided into multiple parts in the circumferential direction.
