。 In a power steering device, the power steering device includes a device that is driven by being directly connected to the steering wheel 2 and discharges oil in proportion to the number of rotations of the steering wheel 2, and a steering valve 4 that determines the flow rate to the steering cylinder 7 based on the amount of oil discharged. A device detects the steering condition of the vehicle body using the return flow rate from the steering cylinder 7, and a signal from this device is used to drain the oil by rotating the handle 2 while the vehicle body is being steered. It has a mechanism that bypasses the oil on the discharge side of the discharge device to the other side,
A power steering device characterized in that a circuit is maintained in a state immediately before oil is allowed to flow into a steering cylinder 7 when a steering wheel 2 is in a stopped state.
