ABSTRACT:
To construct an electric power steering device in which the assist power decreases only the torque required for rotating the steering wheel, while the control of the steering angle of the steered wheels follows basically the rotation of the steering wheel by the driver, except when the steering angle of the steered wheels is changed by an actuation of a vehicle behavior control device, by a tie rod connecting bar supported to make a linear motion, a rotary member rotatable around the tie rod connecting bar, a rotation conversion device for converting a rotation of a steering shaft to a rotation of the rotary member, a rotation/linear motion conversion device for converting a rotation of the rotary member to a linear motion of the tie rod connecting bar, and a power assist electric motor to give a rotational force to the rotary member.
