ABSTRACT:
A shift device for a change-speed gearbox has annular shaped coil spring element, which is closed upon itself in the peripheral direction, is mounted on a synchronizer ring and can be deflected centripetally relative to the rotation axis of a shaft mounting a gear. The deflection is caused by inclined surfaces on teeth of an inner axial coupling toothing of a shift sleeve for the purpose of building up shifting and synchronizing forces.
