Abstract
A steering mechanism is provided, including a rack, a rotatable support member, and an automatically-adjustable support member. The rack includes a rack gear portion and the pinion includes a pinion gear portion coupled with the rack gear portion. The rotatable support member is positioned with respect to the rack or the pinion such that rotation of the rotatable support member adjusts an overlap distance between the rack gear portion and the pinion gear portion. The automatically-adjustable support member automatically urges together the rack and the pinion along an urging direction. The urging direction remains substantially constant throughout the rotation of the rotatable support member within a desired angular range.
