Engine output control device

In an engine output control device that controls an engine output based on a control accelerator-opening degree, only when an amount of change in an instruction accelerator-opening degree is judged to be equal to or larger than a predetermined negative value, and an engine operating condition is judged based on the instruction accelerator-opening degree and an engine revolution number to fall within a predetermined region where an engine output is more likely to change, a control accelerator-opening-degree calculation unit 4 calculates an opening degree by dulling the instruction accelerator-opening degree, as the control accelerator-opening degree.
