<p>In a brake pedal apparatus of the present invention, as a brake pedal 2 is depressed when an engaging means 15 and a receiving portion 14 are engaged with each other, a second lever member 2a2 pivots about a second pivot pin 13. At this point, when the pedaling force Fp is smaller than a threshold value Fp0, the engagement between the engaging means 15 and the receiving portion 14 is maintained so that the second lever member 2a2 pivots about the second pivot pin 13. In this state, the pedal leverage is set to be a smeller ratio. As the pedaling force Fp exceeds the threshold Fp0, the engaging means 15 is disengaged from the receiving portion 14. Then, the first and second lever members 2a1, 2a2 are coupled by a stopper portion 2a3 to pivot together about a first pivot pin 11. Therefore, the pedal leverage is changed to a larger ratio. In this manner, the brake pedal apparatus of which pedal leverage can be easily changed is provided. <IMAGE></p> |
