The present invention provides a vehicle accelerator pedal reaction force control device which may increase an output by a small accelerator opening operation, allows the driving force etc. to be easily controlled by the driver's intention, increases the resistance to the depression of an accelerator to make the driver feel secure, and allows the driver to experience the operational feeling that he or she is operating the vehicle by himself or herself. The vehicle accelerator pedal reaction force control devicehas a first mode in which a relation of the driving force with respect to an accelerator opening is regarded as a predetermined characteristic and a second mode in which the driving force is higher than the driving force in the first mode. In the second mode, the pedal reaction force increases with an increase in the accelerator opening with respect to the first mode.
