An oil pressure control valve for a power steering system is provided to prevent generation of a noise by expanding a hole of a valve housing and by forming a taper part in an inflow port in which operating oil is supplied. An oil pressure control valve for a power steering system includes a valve housing(2) having an inflow port(21) and an outflow port. When the inflow port is connected to the valve housing, an end part of a valve housing side of the inflow port has a taper part(21a). Opening parts are formed in both sides of a hole(2a) of the valve housing connected to the end part. A flow of the operating oil is slow.
