Abstract
PURPOSE: To obtain the steering gear device having variable gear ratio by so constituting that the ratio between the revolution-amount of a pinion element and the actual shift amount of a rack element can be varied without changing several dimensions of the teeth of the pinion element and the rack element.
CONSTITUTION: When a pinion element 3 is revolved through an input shaft 5, the pinion element 3 is shifted in the direction of axis line through the engagement of a spiral groove 7 and an engagement element 14, shifting a rack element 8 through the engagement of the helical gear 6 of the pinion element 3 and the helical gear 9 of the rack element 8. Accordingly, the helical gear 6 of the pinion element 3 slides along the line of teeth, revolving against the helical gear 9 of the rack element 8 and the position of mutual engagement of helical gears is shifted to the direction of axis line, so the actual shift amount of the rack element 8 against the revolution amount of the pinion element 3 is reduced by the amount corresponding to the shift amount. Accordingly, when a steering device having a large gear ratio is necessitated, it is sufficient for the pitch of the spiral groove 7 to be increased.
