置。 A valve placed in the middle of the hydraulic circuit from the brake master cylinder to the rear brake cylinder,
A first valve that controls the opening and closing of this valve and is pushed in the direction of closing the valve by the hydraulic pressure of the hydraulic pressure circuit.
a piston; and a second piston that receives fluid pressure proportional to the load of the vehicle and pushes the valve in a direction to open the valve; a spring is tensioned between the first piston and the second piston; In the load-responsive brake hydraulic pressure control device in which force is transmitted between the two pistons via the first lip, the first lip is directed toward the sliding portion of the first piston in a direction to receive the hydraulic pressure of the brake master cylinder. A load-responsive brake hydraulic pressure control device, further comprising a seal that seals with another second lip facing in the direction of receiving pressure from the second piston side.
