Off-centre yoke for a motor vehicle steering system

An eccentric push member device for a rack-and-pinion steering system of a motor vehicle, the push member device comprising an arcuate rotating pad which has an outer periphery and an inner periphery which is eccentric relative to the outer periphery, the rotating pad being rotatably mounted in a steering casing about an axis of rotation parallel to the longitudinal axis of the rack, the outer periphery of this pad bearing on an arcuate cradle belonging to a support mounted in the steering casing, whereas its eccentric inner periphery is applied against the back of the rack, so as to push back the latter toward the teeth of a steering pinion, said pad being rotatably positioned and/or biased by a clearance compensation mechanism with spring means, wherein the outer periphery of the rotating pad, on the one hand, and the arcuate cradle on the other hand, bear on each other along two spaced contact lines, parallel to the axis of rotation of the pad.
