Zusammenfassung:	A chuck for a drill/driver. The chuck can include an input shaft having a cavity, a chuck actuating shaft and a chuck actuating screw. The chuck actuating shaft can be received in the cavity and can be rotatable about a chuck axis. The chuck actuating shaft can have a threaded aperture. The chuck actuating screw can have a threaded portion that is threadably engaged to the threaded aperture. The jaws can be received in the cavity and can engage the input shaft. The jaws can be coupled to the chuck actuating screw such that rotation of the chuck actuating shaft relative to the chuck actuating screw translates the jaws so that the jaws converge toward or diverge from the chuck axis. The chuck further includes a device coupled to at least one of the chuck actuating screw, the chuck actuating shaft and the input shaft for limiting elastic elongation of the chuck actuating screw in an axial direction when the jaws are positioned in a fully opened condition.
