Abstract
An accelerator pedal is urged in an accelerator closing direction by a hysteresis spring and a return spring. A first increase rate is obtained by dividing an urging force of the hysteresis spring exerted in an accelerator-full-opening position of the accelerator pedal by the urging force of the hysteresis spring exerted in an accelerator-full-closing position of the accelerator pedal. A second increase rate is obtained by dividing an urging force of the return spring exerted in the accelerator-full-opening position of the accelerator pedal by the urging force of the return spring exerted in the accelerator-full-closing position of the accelerator pedal. The second increase rate is smaller than the first increase rate.
