Abstract: A chuck (600) for use with a powered driver having a rotatable drive shaft is provided. The chuck may include a body, a plurality of movable jaws (610), a nut (625), a sleeve (640), and an anti-vibration assembly (620). The anti-vibration assembly may be operably disposed between the sleeve and the nut and configured to absorb vibration caused by operation of the power driver and maintain a position of the sleeve relative to the nut when the sleeve is in at least a locked position.

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.
