Abstract
PURPOSE:To absorb pulsation from a hydraulic auxiliary booster so as to remove a sense of incongruity during operation of a steering wheel by providing at the point of combination of the hydraulic auxiliary booster and the frame of a car a combining means made by an elastic member. CONSTITUTION:When a steering wheel 1 is turned to the left a steering force sensor 3 outputs a detection signal to a program controlling circuit 7 and the program controlling circuit 7 controls a solenoid valve 6a so that a left compensating valve 22a is actuated. By this actuation pressure oil is supplied to the pressure room (a) of a hydraulic auxiliary booster 5 and the pressure oil to which pressure required for steering front wheels 9 is supplied moves a piston 210 and provides an auxiliary force to a steering device 2 via a machine linkage. During transmission of the auxiliary force, a force from the hydraulic auxiliary booster 5 is temporarily transmitted to a combining means and the combining means absorbs pulsation of pressure generated in the hydraulic auxiliary booster 5 and also absorbs pulsation of pressure oil supplied to a reaction hydraulic pressure means 21.
