載のブレーキ液圧保持装置。[Claims for Utility Model Registration] (1) A first port to which a pipe on the master cylinder side is connected and a second port to which a pipe on the wheel cylinder side is connected are formed in the device body; A valve body is provided in the main body of the device to open and close a flow path that communicates the respective ports with each other, and a solenoid is used to open and close the valve body against an elastic force applied to the valve body in the direction of opening the valve body. A push rod that operates in a closing direction is provided in the device main body, and a valve seat member that contacts the valve body and closes the flow path is provided when the pressure of the liquid reaching the flow path from the first port increases. . A brake fluid pressure holding device formed of an elastic material so as to open the flow path away from the valve body. (2) The brake fluid pressure holding device according to claim 1, wherein the valve seat member, including the portion that contacts the valve body, is entirely formed of a rubber material. (3) The valve seat member is formed of a rigid first valve seat having a contact surface that comes into contact with the valve body, and a second valve seat assembled to the first valve seat and made of an elastic material. A brake fluid pressure holding device according to claim 1 of the above-mentioned utility model registration claim.
