An accelerator pedal device includes a pedal reaction force providing device for providing a reaction force to an accelerator pedal according to an amount of depression of the accelerator pedal operated by a driver. The reaction force to be provided from the pedal reaction force providing device to the pedal is controlled based on the depression amount of the accelerator pedal. This reaction force control allows precise agreement between throttle opening timing and pedal reaction force timing to produce a predetermined pedal reaction force at a desired degree of throttle opening.
