In the pressure reducing valve, the pressure set by the adjustment spring 48 is set lower than a predetermined value, and a solenoid 66 is provided below the valve 38, thereby attracting the valve body 40 against the force of the valve spring 42. The pressure reducing valve outputs the excitation current of the solenoid 66 as the operation signal for the feedback control, thereby changing the force that attracts the valve spring 42 to adjust the degree of opening of the valve 38.
