ことを特徴とする前後輪操舵車の後輪操舵装置。 A shaft is connected at its front end to the front wheel steering link mechanism, extends rearward, and rotates or moves forward and backward in response to the steering operation of the front wheels; In a front and rear wheel steered vehicle comprising a coupling mechanism that steers the rear wheels by moving the actuating rod in the left and right directions according to the movement, the coupling mechanism is configured to have a base end thereof pivotable in the longitudinal direction on the vehicle body side. a first link that is supported and extends in the left-right direction above or below the actuating rod and rotates in the front-rear direction as the shaft moves; a second link extending in the left-right direction between the actuating rod and the first link; The second link is rotatably supported in the front and back direction coaxially with the rotation fulcrum of the base end of the first link, and the rotation end is connected to the rotation end of the first link.
a third link supported so as to be rotatable in the front-rear direction coaxially with a rotation fulcrum at the base end of the link; and an actuator that rotates the second link in the front-rear direction about the rotation fulcrum at the base end of the third link. A rear wheel steering device for a front and rear wheel steered vehicle, characterized by comprising:
