Claims

[Scope of utility model registration request]

a first rotary shaft whose front end is connected to the front wheel steering link mechanism, extends rearward and rotates in response to steering operation of the front wheels; and a first rotary shaft whose rear end is connected to the rear wheel steering link mechanism and extends forward. A second rotating shaft that steers the rear wheels by rotation, and a variable steering angle mechanism that connects these two rotating shafts, the variable steering angle mechanism being provided at the rear end of the first rotating shaft. a ball screw, a connecting member fixed to the movable screw member of the ball screw and connected to the front end of the second rotary shaft so as to be able to transmit torque and to be slidable in the front-rear direction; and a connecting member protruding outwardly from the connecting member. A pair of left and right support brackets each having a long hole extending in the front-rear direction into which a pair of left and right arm portions provided therein are inserted and supporting the arm portion so as to be movable along the long hole; and an actuator that tilts the long holes in opposite directions, and the long holes are formed by a linear intermediate portion and a pair of inclined shapes extending substantially parallel to each other from both ends of the intermediate portion. A rear wheel steering device for a front and rear wheel steered vehicle, comprising both ends of.
