ABSTRACT:
A cable-type steering device with electric power-steering assist in which the structure of the steering torque transmitting system is simplified and the loss in transmission of the steering torque is decreased. An output shaft of a motor in an electric power-steering device is rotatably carried around an outer periphery of a steering rod and connected to the steering rod through a ball screw mechanism. A follower pulley, to which a steering torque from a steering wheel is transmitted through Bowden wires, is spline-coupled to an outer periphery of the output shaft of the motor. When the output shaft of the motor is rotated by the steering torque of the steering wheel transmitted to the follower pulley or by the output torque from the motor, the steering rod is moved laterally by the ball screw mechanism to turn the steerable wheels of a vehicle.
