るようになつていることを特徴とするチヤツク。 a flange located approximately in the center and protruding toward the outer periphery;
The sleeve part of the chuck main body consists of a shank part located at one end of the flange and extending in the axial direction, and a tool fitting sleeve part located at the other end of the flange and also extending in the axial direction. A tightening nut having a tapered surface corresponding to the tapered outer circumferential surface of the sleeve portion is rotatably fitted to the outside via a needle roller group inserted so that its axis is inclined with respect to the generatrix of the tapered surface. In the chuck, which grips a tool fitted to the sleeve by elastic deformation of the sleeve, a male thread is formed on the chuck main body on the sleeve side adjacent to the collar, and a reinforcing nut is rotated on this chuck. A chuck characterized in that the chuck is freely screwed together and the reinforcing nut can be tightened in pressure contact with the end face of the tightening nut.
