摘要： A locking arrangement for the selector lever 1 of an automatic transmission locks the selector lever in the neutral positions P and N by the form-locking engagement of a selector-lever-fixed locking member in indentations of a rotatable pawl. An actuating force, which is applied to the selector lever in the locked condition, by way of curved contact surfaces of the locking member, at a contact point, is introduced into steep flanks bounding the indentations. A resulting low supporting force exercises so little stress on two rollers supporting the pawl that, by means of a lifting magnet, one roller, despite the acting actuating force, can easily be displaced in a position which releases the pawl and unlocks the selector lever.
