Abstract
A chuck has a body (14). A plurality of first teeth (96) are rotationally fixed to the body. At least one second tooth (100) opposes the first teeth. The first teeth and the at least one second tooth are configured so that engagement of the first teeth and the at least one second tooth prevents relative rotation between a nut (16) and the body in an opening direction. A sleeve (18) defines a notch (90b) that engages a spring (29) so that in a relative rotational position between the sleeve and the nut, the notch receives the spring so that the notch resists relative rotational movement between the sleeve and the spring in the opening direction of the chuck.
