A travel limiting lever is rockably mounted about an axis at right angles to the axis of the cover assembly and comprises two camming surfaces, one of the camming surfaces being engageable with the reaction plate or flywheel and the other being engageable with the cover. The lever is subjected to resiliently loaded friction action for controlling the angular position of the lever. The camming surfaces are both disposed on the same side of a plane which passes through the axis and also passes through the axis of the cover assembly or is parallel thereto.
