Abstract
A steering system for a motor vehicle which makes gear boxes common for the motor vehicle equipped with the steering system and a motor vehicle not equipped with the same, and which is reduced in size. A stopper engagement portion which restricts a relative rotation within a predetermined angular extent is formed between an input shaft side sleeve and an output shaft side sleeve. A gear ratio changing mechanism which is meshed with both a gear of the input shaft side sleeve and a gear of the output shaft side sleeve is constructed of an input side ring gear which includes an input side gear meshed with the input shaft side gear and an internal gear meshed with an input side planetary gear, an output side ring gear which includes an output side gear meshed with the output shaft side gear and an internal gear meshed with an output side planetary gear, and a planetary gear carrier which rotatably supports the input side and output side planetary gears in a unitary state and which is driven to rotate by a gear ratio changing motor through a reversible rotation gear mechanism.
