ABSTRACT:
A keyless chuck comprises a plurality of jaws slidably fitted respectively in bores formed in a body. A substantially cylindrical, first operating component is mounted on the body rotatably and axially movably, and is provided with female threads in engagement with male threads on the respective jaws. A substantially cylindrical, second operating component is mounted on the first operating component for angular and axial movement. A cam device is arranged between the second operating component and an end member fixedly mounted to the rear end of the body. When the second operating component is angularly moved in a first direction, the cam device moves the second operating component forwardly to cause at least one projection provided on the second operating component to move forwardly the first operating component and the jaws threadedly engaged therewith. When the second operating component is angularly moved in the opposite second direction, the cam device allows the second operating component to be moved rearwardly.
