Abstract
In a brake pedal apparatus, as a brake pedal is depressed when an engaging device and a receiving portion are engaged with each other, a second lever member pivots about a second pivot pin. At this point, when the pedaling force is smaller than a threshold value, the engagement between the engaging device and the receiving portion is maintained so that the second lever member pivots about the second pivot pin. In this state, the pedal leverage is set to be a smeller ratio. As the pedaling force exceeds the threshold, the engaging device is disengaged from the receiving portion. Then, the first and second lever members are coupled by a stopper portion to pivot together about a first pivot pin. Therefore, the pedal leverage is changed to a larger ratio.
