An accelerator pedal apparatus includes an accelerator pedal, a hysteresis generating mechanism which generates hysteresis on pedaling force, a reaction force adding mechanism which adds reaction force to push back the accelerator pedal toward a rest position, and controller which performs drive control of the reaction force adding mechanism, while the controller performs drive control of the reaction force adding mechanism so that reaction force is added during returning as well as during depressing of the accelerator pedal under predetermined conditions as the reaction force being larger than pedaling force difference between pedaling force at the depression side and pedaling force at the return side of the pedaling force hysteresis to obtain an appropriate accelerator feeling and to quickly perform danger avoidance or danger notification.
