Abstract
PURPOSE: To decrease a number of part items while lessening a spool valve size, by directly forming the spool valve part for selecting the hydraulic pressure inside an input shaft.
CONSTITUTION: Steering power, when acted upon an input shaft 2 from a handle, is transmitted to an output shaft 4 through a torsion bar 5 simultaneously tends to rotate a valve body 16 through a ball 21 arranged in a spiral groove 20. However, the valve body 16, being not in a rotatable state by a stopper pin 24, is not rotated but the ball 21 moves sliding along the spiral groove 20 due to the power from the input shaft 2. Accordingly such axially sliding motion of the ball 21 allows the valve body 16 to make only axial sliding without rotating, thus to perform the selecting operation of oil passages in a spool valve part 10 directly formed in the vicinity of the central part of the input shaft 2.
