A control pedal apparatus for adjusting a control pedal of a motor vehicle such for example as a brake pedal, an accelerator pedal, or a clutch pedal. The mechanism includes a pedal arm, an adjustor member, and a bracket secured to the fire wall of the vehicle. The mechanism allows the position of the pedal pad to be adjusted slidably on the adjustor member without disturbing the position of the particular control element actuated by the pedal assembly, and selectively moves the pivot axis of the pedal assembly to maintain a fixed mechanical advantage of the pedal assembly irrespectively of the position of adjustment of the pedal arm on the adjustor member. Coacting slots allow the pivot axis to be selectively moved during adjustment of the assembly but coact in response to depression of the pedal to fix the position of the pivot axis in any adjusted position of the pedal arm so that the pedal assembly pivots positively about the instantaneous assembly axis in any adjusted position of the pedal arm. The adjustment of the pedal arm is accomplished by the rotation of a screw engaging a nut on the pedal arm with the screw being driven by an electric motor.
