A reset spring (33) causes the resetting of an operating unit, where the operating unit is work-connected with the clutch device by a free movement mechanism e.g. free swiveling mechanism, The mechanism has a traction lever (11) and a synchronization lever (28) that are tiltably supported around a common rotation axis. The synchronization lever is rigidly arranged at a clutch shaft.
