Patent ID: 7063180

Claim:
A vehicle steering transmission device for transmitting a vehicle steering operation to a vehicle wheel, comprising, a first gear being rotatable on a rotational axis to rotate in accordance with the vehicle steering operation, a second gear being rotatable on the rotational axis and connectable to the vehicle wheel so that an orientation of the vehicle wheel is changed, an intermediate gear engaging with the first and second gears to transmit a rotation between the first gear and the second gear through the intermediate gear, a support member being rotatable on the rotational axis while supporting the intermediate gear in such a manner that the intermediate gear is rotatable on another rotational axis which another rotational axis intersects the rotational axis and extends perpendicularly to the rotational axis to generate a differential rotational motion between the first and second gears, and a driving device for driving the support member to rotate on the rotational axis so that the differential rotational motion is generated between the first and second gears.
