An electric power steering apparatus () includes a reduction mechanism (G) for transmitting the rotation of a rotating shaft () of a motor () to a ball screw nut () while reducing the speed of the rotation. The reduction mechanism includes a drive gear (), which is coaxially connected to the rotating shaft of the motor, and a driven gear (), which is arranged on the outer surface of the ball screw nut. Due to the reduction mechanism, the motor may be inclined relative to a rack shaft ().

Electronic control power steering device

A four-wheel steering system for an automotive vehicle in which a cable linkage is adapted to operatively interconnect front and rear wheel steering mechanisms. The cable linkage is provided with a displacement transmitting mechanism which includes an input element operatively connected to a front lateral bar in the front wheel steering mechanism through the cable linkage, an output element operatively connected to the rear wheel steering mechanism, and a spring element disposed between the input and output elements to transmit displacement of the input element to the output element without any deflection in a condition where the output element is freely movable and to absorb displacement of the input element in a condition where the output element is restrained by an excessive load applied thereto from the rear wheel steering mechanism.
