ABSTRACT:
An accelerator pedal device comprises a pedal lever having a pivot shaft which is pivotally supported by a fixed support bracket. The pedal lever is biased in such a direction that an upper part of the pedal lever approaches a fixed stopper member. A first auxiliary lever is pivotally supported by the pivot shaft and has a first upper portion located between the stopper member and the upper part of the pedal lever. A second auxiliary lever is pivotally supported by the pivot shaft and has a second upper portion located between the first upper portion and the upper part of the pedal lever. A first lost-motion mechanism is provided between the pedal lever and the second auxiliary lever, and a second lost-motion mechanism is provided between the second and first auxiliary levers. A first switch is arranged to be actuated when an intersection angle between the pedal lever and the second auxiliary lever becomes smaller than a first given angle and a second switch is arranged to be actuated when an intersection angle between the second and first auxiliary levers becomes smaller than a second given angle.
