<p><P>PROBLEM TO BE SOLVED: To provide a brake pedal device a lever ratio characteristic of which is changed in correspondence with leg-power, capable of restraining dispersion of an original position of an operation pedal due to a dimensional error and an assembling error of a part and rattling of the operation pedal. <P>SOLUTION: The lever ratio characteristic is devised to be changed as a revolving member 36 is arranged on a change-over lever 28 and a revolving center of the revolving member 36 is switched to a second shaft 22 from a third shaft 34 in correspondence with the leg-power. Consequently, it is possible to restrain dispersion of the original position of the operation pedal 26 caused by the dimensional error, the assembling error, etc. of the part and rattling of the operation pedal compared with the case changing the lever ratio characteristic by changing the revolving center of the operation pedal 26 by arranging the operation pedal 26 on a pedal bracket 16 free to revolve around a previously specified constant first shaft 20. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
