摘要： A turning device that can be combined with a suspension mechanism without requiring significant modification to existing suspension mechanisms, and that provides a compact design when combined with a suspension mechanism. In a turning device according to the present invention, a main device unit, containing a turning motor and a differential speed reducer, and a turning output member that rotates relative to the main device unit are positioned roughly co-axially with a kingpin shaft. This makes it possible to reduce the amount by which the turning device projects in the direction perpendicular to the kingpin shaft. As a result, compared to conventional technologies, the turning device can be combined without significantly modifying the structure of an existing double wishbone suspension mechanism, and the overall structure that combines the double wishbone suspension mechanism and the turning device can be made compact.

摘要： A strain wave reduction gear and a variable transmission ratio steering apparatus move a flexible gear and a rigid gear differentially, even if the flexible gear is in a fractured state. According to the strain wave reduction gear, the flexspline mates with the inner side of the elliptical hole of the rigid cam via the flexible bearing; therefore, the flexspline maintains an elliptical shape that is similar to the elliptical hole and maintains the meshed state—even if the flexspline fractures. Therefore, when the rigid cam rotates, the mesh positions of the flexspline and the first and second circular splines can be shifted in a circumferential direction. Namely, even in a state wherein the flexspline is fractured, the first circular spline and the second circular spline can be moved differentially by the difference in their tooth counts.

摘要： A cam follower includes an oval rotational body which is rotationally supported on a fixed pin, and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove, and a short axis of the oval is shorter than the width of the cam groove, the oval rotational body being biased and being rotated by a biasing spring in one direction about the fixed pin. As a consequence, when a steering wheel is in a neutral position, the outer circumferential surface of the cam follower comes into contact with both side surfaces of the cam groove in the width direction of the cam groove and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.
