Claims

[Scope of utility model registration request]

a rotary shaft that rotates in response to steering operation of the front wheels; an actuating rod that is attached to the vehicle body so as to be movable in the axial direction and rotatable around the same axis and rotated by the rotary shaft; a cam follower provided on the vehicle body and extending along a second axis perpendicular to the axis of the actuating rod at a neutral position; A rear wheel steering device for a front and rear wheel steered vehicle, comprising a cam having mating cam grooves and a drive means for rotating the cam, the rear wheels being steered by axial displacement of the operating rod.
