Abstract
A brake pedal apparatus includes: an operating pedal to be depressed so as to be pivoted about a first axis; a pivot member pivotable about a second axis parallel to the first axis, and connected to the operating pedal via a connecting link so as to be pivoted about the second axis in response to a depression of the operating pedal; and an output member to receive an output generated upon pivot motion of the pivot member. The connecting link is connected, at respective connected positions, to the operating pedal and the pivot member. A relationship between a ratio of the output to a depression force acting on the operating pedal, and an amount of the depression of the operating pedal is changed depending upon the connected positions of the connecting link. The brake pedal apparatus further includes a ratio characteristic changing device operable, when the depression force exceeds a predetermined value, to shift at least one of the connected positions of the connecting link, for changing the relationship between the ratio and the amount of the depression of the operating pedal.
