。 Using a steering unit that is directly connected to the steering wheel and driven to direct a pilot flow rate proportional to its rotational speed to the steering valve, pressure oil from the steering pump and switch pump is supplied to the steering cylinder through the steering valve. In the steering hydraulic circuit, pilot oil passages communicating between the metering valve in the steering unit and the left and right pilot pressure receiving parts of the steering valve are connected via a pressure transmitter-like absorb valve, and A steering circuit for a wheel-type construction machine, characterized in that the amount of sliding movement of a piston within the absorb valve is configured to be adjustable.
