ABSTRACT:
A liquid pressure control device (1) including a valve mechanism for reducing liquid pressure of a brake master cylinder at a predetermined ratio by a pair of plungers (3, 4) moved independently by liquid pressure from the brake master cylinder through ports (7, 8) and for transmitting the reduced pressure to brake cylinders, of right and left rear wheels through ports (9, 10), respectively, and a load sensing mechanism (11) for having a load according to a movable load of a vehicle act on respective plungers (3, 4) so as to move a pressure reduction starting point of the valve mechanism. The load sensing mechanism (11) has a spring (12) connected to an axle side at one end thereof for transmitting energizing force according to the movable load of the vehicle, a load sensing lever (13) pivotally supported on a housing of the valve mechanisms (5, 6) at one end thereof and connected to the other end of the spring at the other end thereof, an equalizer (14) abutting against ends (3a, 4a ) of respective plungers (3, 4), and a clamp member (15) for attaching the equalizer fixedly at a predetermined position of the load sensing lever and preventing the equalizer from coming off due to a large movement of the load sensing lever.
