Claims

[Claims for Utility Model Registration] A pair of first and second master cylinders M ₁ ,
_M2 , brake devices BFL, BFR, BRL,
BRR, _the brake _device B
In a vehicle brake hydraulic control device in which interlocking hydraulic pressure generating means 4 ₁ , 4 ₂ that can apply braking hydraulic pressure to FL, BFR, BRL, and BRR are interposed, the interlocking hydraulic pressure generating means 4 ₁ , 4 ₂ have a partition wall between them. A body 5 having coaxial first and second cylinder holes 7 and 8 with a cylinder 6 interposed therebetween, and a first input hydraulic chamber 17 communicating with the first master cylinder _M1 are connected to the first cylinder on the opposite side of the partition wall 6. A first piston 9 is slidably fitted into the first cylinder bore 7 while being defined between the first piston 9 and the end wall of the bore 7, and a second piston ₉ communicating with the second master cylinder M2.
The input hydraulic pressure chamber 24 is formed on the partition wall 6 side, and the brake devices BFL, BFR, BRL, BRR
A second piston 10 is slidably fitted into the second cylinder hole 8 while forming an output hydraulic chamber 25 communicating with the second input hydraulic chamber 24 on the opposite side of the second input hydraulic chamber 24, and a piston rod 11 that coaxially connects both pistons 9 and 10 while penetrating the piston rod so as to be movable in a direction; a first and second input hydraulic chamber 17;
