Abstract:
A motor vehicle steering system includes a transmission ratio variable mechanism capable of changing a transmission ratio, and a steering-assist-force imparting mechanism. The transmission ratio variable mechanism is provided with an input member and an output member capable of rotation about a first axis, a first bearing ring for differentially rotatably coupling to each of the input and output member, a second bearing ring for rotatably supporting the first bearing ring via a rolling element, and an electric motor for rotation-driving the second bearing ring. A second axis that is a center line of the first bearing ring and the second bearing ring is inclined relative to the first axis.
