Claims

[Scope of utility model registration request]

Inside the cylinder installed in the vehicle's brake fluid pressure transmission system,
A plug is inserted to form an input liquid chamber on the mask cylinder side and an output liquid chamber on the brake device side, and only the pressure liquid flows from the input liquid chamber to the output liquid chamber between the opposing peripheral surfaces of the plug and the cylinder. The brake fluid pressure is controlled fluid-tightly by pistons and couplings that allow the brake fluid pressure to flow, and a switching valve is interposed between the input fluid chamber and the output fluid chamber that is normally open and closed by the operation of the electromagnetic actuating mechanism. A brake fluid pressure holding device, wherein the input and output fluid chambers are bypass-connected via a check valve that allows pressure fluid to flow from the input fluid chamber to the output fluid chamber.
