Abstract
An impact drive assembly (110,210) for an impact driver (100) is provided that includes an anvil (115,215), a hammer (112,212), a camshaft (111,211), and a stability bearing. An interior surface of a hammer channel (114,214) in the hammer head (121,221) may comprise a hammer movement surface (123,223). The camshaft (111,211) may comprise a camshaft movement surface (125,225) and a rotational input interface (127,227). The camshaft (111,211) may extend through the hammer channel (114,214), such that, due to operable coupling of the hammer movement surface (123,223) with the camshaft movement surface (125,225), movement of the hammer (112,212) relative to the camshaft (111,211) may cause the hammer head (121,221) to repeatedly impact an anvil lug (120, 220) with a rotational and axial force. The stability bearing may be disposed in contact with and between the interior surface of the hammer channel (114,214) and an exterior surface of the camshaft (111,211) to permit relative rotational movement and provide radial support via contact with the camshaft (111,211) and the hammer (112,212).

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.
[Problem] To provide a chuck device that has a simple structure and that can be reliably locked. [Solution] A chuck device (1) that is provided with: a plurality of balls (41); a retainer (42) that rotatably holds the balls (41); a spring ring (34) that rotates together with a nut ring (33) and that is configured so as to be switchable between a rotation restriction state in which a loosening direction (L) with respect to the retainer (42) is restricted and a restriction release state in which the restriction of the loosening direction (L) with respect to the retainer (42) is released; and a one-way spring (31) that restricts the loosening direction (L) of the retainer (42) with respect to a chuck body (11). A one-way bearing mechanism (50) in which the loosening direction (L) is restricted between the nut ring (33) and the chuck body (11) is configured using the plurality of balls (41), the retainer (42), and the one-way spring (31), and a bearing and lock mechanism (30) is configured using the retainer (42) while in the rotation restriction state.
