Abstract
Abstract A clutch release for motor vehicles or the like includes a clutch operating means and a clutch disengaging means and a clutch disengaging means. A bearing is operatively associated with the clutch disengaging means for operating the latter. An energy storage device provides a biasing force urging the bearing means into contact with a stop. The clutch operating means is operable to lift the bearing means from the stop whereby the bearing means is moveable in a radial direction for centering. A positive connection is provided between the bearing and the stop when the bearing and stop are biasingly urged into engagement with one another.
