Abstract: A steering damper has a pair of damper portions each including a variable throttle valve for restricting inflow from a power cylinder into a flow passage change-over valve, the variable throttle valve provided on the way to each cylinder passage and a first check valve for permitting inflow from the flow passage change-over valve into the power cylinder, the check valve connected in parallel with the variable throttle valve. The steering damper has a second check valve in communication to a tank between the first check valve and left and right chambers of the power cylinder.
