Abstract: An accelerator pedal device includes a pedal arm, a liner, a hysteresis lever, and a spring. The pedal arm is pivotally supported on a housing and tilted by accelerator manipulation. The liner is formed on the pedal arm in the vicinity of a pivoting point of the pedal arm. The resilient hysteresis lever is engaged with the housing to cross the pedal arm. The hysteresis lever includes a sliding portion sliding on the liner. The spring is interposed between a pedal arm side opposite to a point of force to which an accelerator manipulation force is applied of the pivoting point regarding the pedal arm and a side of the hysteresis lever opposite to a portion engaged with the housing regarding the sliding portion. The spring elongates and contracts in response to tilting of the pedal arm to generate a reaction force and a hysteresis load.
