Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motor-driven power steering device capable of detecting an accurate steering angle, based on a turning angle.SOLUTION: A microcomputer 31 includes a turning angle estimation part 41 for detecting the turning angle t generated in a turning wheel, based on left and right wheel speeds Wr, Wl, and a steering angle conversion part 42 for detecting the steering angle s generated by steering, by converting the turning angle t. The steering angle conversion part 42 converts the turning angle t into the steering angle s, based on a steering gear ratio R.
