Clutch pedal devices are known which comprise a rotatably mounted clutch pedal and means for generating a specified pedal force curve over the pedal path, said means comprising a pedal arm which is non-rotatably connected to the clutch pedal and which can be moved against a spring force of a helical spring. Disadvantageously, only a linearly increasing pedal force curve over the pedal path can be achieved using said design. Thus, a pedal sensation is produced which strongly deviates from the pedal sensation produced when using a conventional clutch pedal which hydraulically actuates the clutch. In the clutch pedal device according to the invention, the pedal force curve over the pedal path also has a section with a negative slope after a section with a positive slope. In this manner, a pedal sensation is produced which strongly resembles the pedal sensation when actuating a conventional clutch pedal which hydraulically actuates the clutch. According to the invention, the pedal arm (3) acts on a rotatably mounted lever arm (5), to which a counter force is applied, and is moved on a contour (6) of the lever arm (5) when the clutch pedal (1) is actuated.
