PURPOSE:To make attractive force property of a spool non-linear against currents applied to a solenoid of a solenoid fluid pressure valve by providing at an end of either of a spool and a yoke arranged close to each other with a circumferential cut. CONSTITUTION:While an outer circumferential end of a spool 11 and an inner circumferential end of a yoke 30 of a solenoid fluid pressure valve are arranged close to each other, a circumferential cut A is formed on the outer circumferential part of the spool 11. This makes attractive force property of the spool 11 non-linear against currents applied to a solenoid 20. Accordingly, when this valve is arranged on a fluid passage for reaction force control of a power steering device, changes in reactional hydraulic pressure forces acting on a reactional force mechanism against currents applied to the solenoid 20 can be made ideal.
