Inventor: WACHI YUJI
IPC: B60T7/06
Filed: 2002-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a brake pedal device, capable of changing a pedal ratio easily. SOLUTION: Applying a brake pedal 2 in an engaging state with an engaging means 15 and a part 15 to be engaged makes a second lever member 2a2 rotate pivoting a second rotational axis 13. In this case, when a pedal depressing force Fp is not greater than a setting value Fp0 , the engagement state with the engaging means 15 and the part 14 to be engaged is held, and the second lever member 2a2 rotates pivoting a second rotating axis 13. In this way a small lever ratio is set. When the pedal depressing force exceeds the setting value Fp0 , the engaging means 15 is disengaged from the part 14 to be engaged. As a result, the first and second lever members 2a1 , 2a2 are integrally combined with a stopper part 2a3 . Thereby the lever ratio is changed so as to set a large lever ratio.
