Abstract: A driving assistance device enables a driver who manually performs an accelerator operation and a steering operation to easily retain an accelerator operation state in a constant state. A driving assistance device includes a manually operable accelerator operation unit in the vicinity of a steering wheel provided in front of a driver seat in a vehicle cabin. The accelerator operation unit is operable in a state where the steering wheel is gripped and an operation reaction force of the accelerator operation unit exhibits an inflection point POI at which the operation reaction force rapidly becomes large in response to an increase in an operation amount of the accelerator operation unit.
