。[Claims for Utility Model Registration] (1) It has first and second brake hydraulic systems that supply braking hydraulic pressure to each of the front wheel cylinder on the front wheel side and the rear wheel cylinder on the rear wheel side, and during normal operation, When the hydraulic pressure generated by the hydraulic sources of the first and second brake hydraulic systems reaches a predetermined value depending on the hydraulic port opening degree corresponding to the depression input of the brake pedal, the valve body of the hydraulic pressure control valve section closes the oil passage. act to reduce the brake hydraulic pressure supplied to the rear wheel cylinder by throttling the hydraulic pressure from the hydraulic pressure source of the second brake hydraulic system, and when the first brake hydraulic system fails, both brake hydraulic pressures are reduced. The valve body operates in the direction of opening the oil passage due to the differential pressure generated between the systems, thereby communicating the second brake hydraulic system and the rear wheel cylinder, and supplying braking hydraulic pressure to the rear wheel cylinder. A brake fluid pressure control device featuring: (2) The brake fluid according to claim 1, wherein the valve body is provided so as to be movable on the same axis inside a spool valve constituting the second brake hydraulic system. Pressure control device.
