の後輪操舵装置。[Scope of claim for utility model registration] A vehicle having a front wheel steering means for steering the front wheels and a rear wheel steering means for steering the rear wheels, transmitting the front wheel steering angle to the rear wheel steering means and corresponding to the transmitted front wheel steering angle. A rear wheel steering device for a front and rear wheel steered vehicle configured to steer the rear wheels in a direction opposite to that of the front wheels, wherein the front wheel steering angle inputted to an input shaft is adjusted to a gear ratio according to the steering angle. The first sector gear changes.
a first front wheel steering angle transmitting means for transmitting the amount of rotation to the sector shaft of the first sector; and a gear ratio of the first sector gear according to the amount of rotation transmitted to the first sector shaft. a second front wheel steering angle transmission means for transmitting the front wheel steering angle in the axial direction as a longitudinal movement amount from the input shaft to the transmission shaft described later by a second sector gear whose gear ratio changes differently from the input shaft; a third front wheel steering angle transmitting means for transmitting an amount of rotation to the transmission shaft; converting the transmitted amount of rotation into an amount of longitudinal movement by meshing with the second sector gear; and a transmission shaft for transmitting the difference between the longitudinal motion amount transmitted by the second front wheel steering angle transmission means to the rear wheel steering means as a rear wheel turning amount, after the difference is transmitted from the transmission shaft. The front and rear wheels are characterized in that the rear wheel steering means is operated in accordance with the amount of wheel turning, and when the front wheel steering angle exceeds a predetermined angle, the rear wheels are steered in the opposite phase. Rear wheel steering device for wheel steering vehicles.
