Abstract

PURPOSE: To operate smoothly a valve spool irrespective of quality of material by disposing the valve spool between an input shaft and torsion bar of a power steering device for a vehicle to carry out transmissive connection between the input shaft and valve spool by means of balls and a ball groove.
CONSTITUTION: When steering force of a steering wheel is applied to an input shaft 2, torque is transmitted from a torsion bar 4 through a connecting pin 5 to a pinion shaft 3, while balls 8 slide along a spiral ball groove 7 as the input shaft 2 rotates. Thus, while the input shaft 2 is angularly displaced relatively to a valve spool 6 through the balls 8, the valve spool 6 is eventually slid in the axial direction of the input shaft 2 by pivotal restriction of the pinion shaft 3 to change over an oil supply path between oil grooves 12W14. Thus, the oil pressure change-over section is constituted between the input shaft and valve spool to operate the valve spool smoothly irrespective of the quality of material thereof.
