舵取装置。In a power steering device equipped with a spool valve that is controlled to move forward and backward from a neutral position in conjunction with the steering wheel, and thereby switches the fluid circuit and controls the supply and discharge of pressurized fluid to and from the power cylinder, a pair of pistons and a spool valve are used. A reaction force chamber is provided between the pistons, which has a resilient compression spring, and whose internal volume is compressed when one of the pistons is moved as the spool advances and retreats. By applying air pressure or vacuum depending on the traveling speed or depending on the vehicle speed and steering resistance, a reaction force is applied to the spool to oppose its displacement from its neutral position, and the steering wheel is operated. A power steering device characterized by applying a reaction force.
