Abstract: PURPOSE:To provide a steering system low-priced and excellent in responsiveness without impairing a feeling of physical disorder to a driver at the time of changing a transmission ratio and without requiring to use a powerful actuator with high accuracy. CONSTITUTION:When a driver provides a steering wheel 1 with a steering angle, a steering rack 5 is moved linearly by a pinion 3, and a sliding pin 14 engaged with an elongated hole 13 provided at an oscillating lever 11 rotates the oscillating lever 11 around a fulcrum pin 16 so as to linearly move a relay rod 9 pivotally fixed to the oscillating lever 11 by a pin 12, thus providing steered wheels 6 with an actual steering angle. Accordingly, when the position of the fulcrum pin 16 is moved in the orthogonal direction to the steering rack 5 and relay rod 9, the ratio of the distance (a) and (b) is changed to change the transmission ratio of a steering system. When the transmission ratio is changed in a neutral position as shown in the drawing, the moving resistance of the fulcrum pin 16 is small, and the oscillating lever 11 is vertical to the steering rack 5 in the neutral position of the steering wheel, so that positioning accuracy does not have to be high in this steering system.
