An accelerator pedal device includes: an accelerator pedal; a reaction force
application
device that applies a reaction force to the accelerator pedal; and a selection
device that selects a characteristic between a first characteristic according to
a running situation of a subject vehicle and a second characteristic specified
regardless of the running situation of the subject vehicle. The first characteristic
and the second characteristic each is a characteristic indicating a relationship
between an amount of stepping upon of the accelerator pedal and the reaction force
to be applied. The reaction force application device applies the reaction force
to the accelerator pedal based upon the characteristic selected by the selection device.
