Claims

[Scope of Claim for Utility Model Registration] A pair of small-diameter cylinders provided near the center of the housing, a pair of large-diameter cylinders facing each other with the small-diameter cylinders in between, and a pair of large-diameter cylinders placed inside the large-diameter cylinders and facing each other. The valve seat is divided into an inner output liquid chamber and an opposite input liquid chamber on the outer side, and a cylindrical cylinder with a bottom on the outside, with the center side slidingly fitted to the small diameter cylinder and the outer side abutting against the valve seat. A pair of control pistons, the inside and outside of which are connected to the output liquid chamber, and the control pistons are slidably fitted to the cylinder parts of the control pistons to receive the hydraulic pressure of the output liquid chamber, and can approach each other by a certain distance. It has a pair of auxiliary pistons provided in the valve seat, and a corner spring that biases the auxiliary pistons in the direction toward the valve seat, and the pair of auxiliary pistons and the pair of control pistons are located on one side of each other. A dual piping type brake fluid pressure control device for a vehicle, characterized in that an auxiliary piston on one side and a control piston on the other side are interlocked and interlocked to interlock with each other.
