Abstract

PURPOSE: To provide a rack and a pinion which are readily machined and smoothly in a variable gear ratio type steering device by employing a spur gear having tooth shape of the same configuration circumferentially as the pinion in a manner of providing tapered pinion varied in shifting amount of axial direction.
CONSTITUTION: The pinion shaft 10 of a rotary valve type hydraulic power steering device is connected via a pin 15 to a torsion bar 12 and also connected via a pin 16 to a valve sleeve 13. The stub shaft 11 to be connected to a handwheel shaft is connected via a pin 17 to the bar 12 and also connected via a pin 18 to a valve spool 14. A pinion 1 of spur gear is provided at the pinion shaft 10 and formed in tapered pinion having tooth shape of the same configuration continuously varied axially at shifting position along the handwheel shaft in engagement with a rack 2. The rack 2 is so formed as to have a gear ratio of minimum at maximum pressure angle and pitch, and vice versa.
