Abstract

PURPOSE: To enable setting of the rotational resistance of a steering main shaft in low-speed operation to be smaller than that in high-speed operation by providing a spring element and a pre-pressurizing device which comprises an oil pressure chamber fed with an oil pressure corresponding to the engine revolution rate.
CONSTITUTION: The difference in the engine revolution rate between low-speed operation and high-speed operation is taken up as the difference in the discharge oil pressure of an engine oil pump. With the discharge oil pressure fed to an oil pressure chamber 6 through an orifice 14, the pressure co-operates with a compression coil spring 13 to press a rack bar 6 through a rack guide 8, the pressing force changing between low-speed operation and high-speed operation. The rack guide 8 is pressed against the rack bar 6, the support rigidity of the bar 6 at the portion is engagement with a pinion 3 is increased, the backlash between the pinion 3 and a rack 7 is reduced, and the noise is prevented.
