る前後輪操舵車の後輪操舵装置。 In a rear wheel steering device for a front and rear wheel steered vehicle comprising an electric steering angle ratio setting device for setting a steering angle ratio between front wheels and rear wheels, the drive means for the electric steering angle ratio setting device includes a sun gear, a carrier, and a sun gear. a planetary gear mechanism including three elements of a ring gear; a first electric motor connected to one element of the planetary gear mechanism via a first worm gear whose power transmission efficiency from the wheel to the worm is zero; a second electric motor connected to other elements of the planetary gear mechanism via a second worm gear with zero power transmission efficiency from the wheel to the worm; and an output shaft connected to the remaining elements of the planetary gear mechanism. The front and rear wheels are equipped with a drive means configured to rotationally drive a rotated body that sets the steering angle ratio at the output shaft by energizing the first or second electric motor. Rear wheel steering device for steered vehicles.
