An electric power steering device (1) causes the electric motor (7) to generate auxiliary torque in accordance with the largeness of steering wheel torque by the steering operation of a wheel (9) made by a driver and reduces the steering wheel torque to the driver.

Moreover, large steering wheel torque is requisite at the time of low-speed running, and a steering at a high resolution is requisite at the time of fast-speed running. Accordingly, this does not affect the steering feeling to the driver.
