力舵取装置。A pinion attached to the input shaft is engaged with the rack connected to the wheel, a bearing gap is provided so that the input shaft can be displaced within a minute range parallel to the rack, and the displacement of the input shaft is controlled by a lever on the spool of the control valve. In a power steering device, a power cylinder is connected to the rack, and a power cylinder is connected to the rack, and a piston is connected to the rack via a rond located at an end of a control spool. Two reaction force chambers are defined by a partition wall provided between the spool end and the piston and penetrated by a Rondo, and the pressure receiving areas of the piston and the spool are set to be the same, while a switching valve is provided that is displaced according to the vehicle speed. The switching valve is configured to allow both of the reaction force chambers to communicate with each other in a low speed range, and to selectively introduce high pressure from the operating port into the reaction force chamber that opposes the displacement of the spool in a high speed range. Features a power steering device.
