Abstract
A return-m-neutral mechanism for a rear wheel steering device for an electronically controlled four wheel steering vehicle, in which a spring provided in the return-to-neutral mechanism does not come into operation within a predetermined steering angle range corresponding to the most frequent occurrences in actual application, thereby achieving energy saving and improving response characteristics. In the return-to-neutral mechanism for the rear wheel steering device for restoring the steered rear wheel to its neutral position under the biasing force of the spring, a dead zone corresponding to a predetermined steering angle of the rear wheels is provided for the spring.
