[Scope of Claim for Utility Model Registration] Based on an accelerator operation amount detection means for detecting an accelerator operation amount, an engine output increase/decrease means for increasing or decreasing engine output, and an accelerator operation amount detected by the accelerator operation amount detection means. In an engine equipped with an engine output control means for controlling the output of the engine output increase/decrease means with preset control characteristics, a power steering failure detection means for detecting a failure of the power steering device; Therefore, when a failure of the power steering device is detected, engine output characteristic changing means is provided for changing the control characteristic of the engine output control means so that the output of the engine output increasing/decreasing means with respect to the accelerator operation amount becomes smaller than normal. An engine control device characterized by:
