装置。A flow rate control device for a power steering device that controls the flow rate of working fluid sent to the power steering device from a supply passage leading to a pump via a delivery port, the flow rate control device comprising: , a throttle passage provided on the circumference radially spaced from the center of this fluid passage, a fixed throttle provided upstream of this throttle passage, and a surplus flow caused by sliding due to the pressure of the working fluid before and after the throttle passage. A flow rate adjustment spool is provided to adjust the opening degree of the bypass passage that recirculates the fluid to the inlet side of the pump, and a control spool that slides depending on the pressure of the working fluid before and after passing through the fixed throttle is provided. 1. A flow rate control device for a power steering device, characterized in that a cylindrical portion is formed to narrow a passage so as to partially block it.
