PURPOSE:To prevent an action delay of an inertia valve by providing liquid path openings on an inertia ball container in front and back of the ball, connecting the front opening to a rear wheel brake device, and applying a liquid pressure to the ball. CONSTITUTION:A distribution valve, composed of a control piston 17 and a balance piston 13, is applied with a pressure from a regulating piston 27 controlled by an inertia valve 32. The inertia valve 32 is operated by an inertia ball 36, which moves on a guide plane 35. Liquid path opening 40, 39 are formed in front and back of an inertia ball contaiver, and are connected to a rear wheel cylinder and the distribution valve respectively. Therefore, the inertia ball 36 is applied with a brake liquid pressure. When a brake is applied urgently, the liquid pressure becomes great, and an action delay of the inertia valve is avoided. |
