A pedal-load lightening apparatus comprising a pedal arm and a lever rockable in one therewith. A torsion coil spring is provided between the lever and a support bracket. The coil spring urges the pedal arm to return to its initial position before the arm, starting from the initial position, reaches a neutral position at a predetermined rotational angle to the initial position. When the neutral position is reached, the spring starts to urge the pedal arm in a treadling direction. Moreover, an urging element is attached to the support bracket or the lever. The urging element is adapted to press the pedal arm in the treadling direction, with a force smaller than the repulsive force of the torsion coil spring, within a stroke of the arm between the initial position and a position near the neutral position.
