<p>PURPOSE:To attain miniaturization of the device by providing a new mechanism to mechanically convert rotational movement of a transmitting shaft to transmit steering motion of two front wheels to two rear wheels to movement in the axial direction of rear wheel steering rods. CONSTITUTION:A ball screw shaft 13 which is eccentric by a decided eccentric quantity delta against an input shaft to be transmitted rotational movement of a transmitting shaft, and a nut member 14 moving in the axial direction accompanied with the rotational movement, are provided. Cam faces 14a, 14b are formed on the outside of the nut member 14, movement of cam followers 15, 15 rollingly contacted with them are taken out to rear wheel steering rods 70 through follower holders 16 and hence the two rear wheels are steered.</p> |
