PROBLEM TO BE SOLVED: To provide a reaction force control device for accelerator pedals for vehicles which enables an operator to recognize a case where a pedal operation position is within a predetermined range and a case where the position is deviating from the predetermined range.SOLUTION: The reaction force control device for accelerator pedals for vehicles includes a reaction force generation means, which generates a reaction force of an accelerator pedal 110, and a reaction force control means, which sets up a reaction force to an operation amount of the accelerator pedal 110. The reaction control means increases the reaction force at a constant change rate in a predetermined operation amount range, decreases the reaction force at a change rate larger than the constant change rate in the lower limit value of the predetermined operation amount range, and increases the reaction force at a change rate larger than the constant change rate in the upper limit value of the predetermined operation amount range.
