PURPOSE:To ensure that when the difference between fluid pressures generated respectively in separate brake fluid pressure circuits exceeds a preset value, an actuating means belonging to the high pressure side is displaced toward a proportional pressure-reducing means belonging thereto to cancel the function of the latter, and when said difference returns to or below the preset value, the actuating means is automatically returned to and heald at its neutral position. CONSTITUTION:Left and right bodies 101, 201 of a brake fluid pressure controlling mechanism 1 are connected to each other at a central part by bolts 70, and contain fluid pressure controlling mechanisms 100, 200. A floating shaft 17 is provided at a central part so that,when a difference is generated between the fluid pressures in the systems, the function of the fluid pressure controlling mechanism in the other system is canceled. The mechanisms 100, 200 are provided in bores 103-107, 203-207 gradually enlarged toward the central part, and accordingly, it is unnecessitated to provide a liquid-sealed closed part at end parts of the bodies 101, 201. |
