The present invention provides a pressure reducing valve comprising a valve body, an armature, a plunger, a valve seat, an opening and closing device and an elastic member. The valve body includes a valve flow path connected to a flow path of a wheel cylinder and a flow path of an accumulator. The armature is received in the valve body. The plunger is coupled to the armature in such a manner that the plunger is interlocked with an operation of the armature to reciprocally be moved. The valve seat is arranged on the valve flow path and includes a valve hole communicating with the valve flow path. The opening and closing device is arranged on the interior of the valve seat to close and open the valve hole. The elastic member is in contact with the opening and closing device to be arranged on the interior of the valve seat and applies elastic force to the opening and closing device. The pressure reducing valve is a normal opened (NO) type-valve and is figured to allow oil to flow in the direction that the opening and closing device is pushed, thereby reducing linear pressure reduction.
