An apparatus for adjusting the relative positions of a first component and a second component of a power tool includes a drive rod which interconnects the first and second component. The drive rod has a plurality of external threads in meshing engagement with a plurality of internal threads located on one of the first and second components. An internally threaded element preferably in the form of a backlash nut is also in meshing engagement with the plurality of internal threads. A biasing member is interdisposed between the internally threaded element and one of the first and second component. In a preferred form, the apparatus is incorporated into a power tool for woodworking or metal forming and is operative for eliminating play in the threaded interconnection of the components which is most evidence upon reversal of movement of the drive rod.
Dispositif d'ajustement des positions relatives de deux composants d'un outil électrique à l'aide d'une tige d'entraînement servant à les reliant. La tige comporte des filets externes à engagement par engrènement dans les filets internes de l'un des composants. Un élément à filets internes, de préférence un écrou de compensation, s'engage aussi par engrènement dans les filets internes. Un membre de biais est placé entre l'élément à filets internes et l'un des deux composants. Le dispositif, utilisé de préférence avec un outil électrique pour travailler le bois ou façonner le métal, élimine le jeu dans l'interconnexion filetée des composants, surtout lorsqu'on inverse le mouvement de la tige d'entraînement.
