a normally-closed second solenoid valve that is interposed in a path from the downstream side of the solenoid valve to the reservoir device and opens the path in response to a brake hydraulic pressure reduction or pressure increase signal during antilock control; 2 The oil pressure in the reservoir oil chamber connected to the solenoid valve is reduced by a piston that moves depending on the oil pressure in the control oil chamber.
It is provided with a built-in movable piston that pressurizes and holds it as necessary, and the control oil chamber of this reservoir device is
Brake hydraulic pressure increase and decrease during anti-lock control,
Furthermore, in an anti-lock control device connected to a pressure oil source and a release tank via a solenoid valve device that supplies and discharges pressure oil by inputting a hold signal as necessary, the brake fluid pressure transmission path and the reservoir of the reservoir device are connected to each other. 1. An anti-lock control device for a vehicle, characterized in that a branch path is provided between the oil chamber side and the brake oil chamber side, and a check valve is provided in the branch path to allow only brake pressure oil to flow from the reservoir oil chamber side.
