摘要： A chuck (1) for a tool which is attached to a clamped part (8) of the main unit (2) of the chuck, wherein a retainer (3) for holding a large number of needle rollers (32) around the clamped part and a clamping sleeve (5) are rotated to clamp and fix the tool in the attached state. The retainer is composed of four separate retainer parts (4a to 4d), and the separate retainer parts have a movement adjusting mechanism that allows the separate retainer parts to move to appropriate clamping positions. Movement of the separate retainer part located closest to the tip end of the retainer is limited.
