TRANSMISSION RATIO VARIABLE STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transmission ratio variable steering device, producing a reduction in manufacturing cost while securing the function of a gear mechanism. SOLUTION: In the transmission ratio variable steering device 1 for varying a transmission ratio between a steering angle and a rotational steering angle, a wave gear mechanism 5 has a wave generator 17, a flexible spline 19, a stay circular spline 20 and a drive circular spline 21. The stay circular spline 20 is pressed into a housing 7. The drive circular spline 21 is pressed into a movable flange 72b of a lower steering shaft 72. COPYRIGHT: (C)2004,JPO
