Claims

[Scope of utility model registration request]

A hydraulic control valve controls the brake fluid pressure transmitted from the mask cylinder to the rear wheel brake system of the vehicle at a turning point, and an inertia ball moves and hits the valve seat when the deceleration during vehicle braking exceeds a certain value. and an inertia valve that seals a sealing fluid chamber communicating with the brake fluid pressure system by fitting the brake fluid pressure system, and varies a corner value of the pressure reduction control in proportion to the value of the sealing fluid pressure. In a deceleration sensing type hydraulic pressure control device for a brake system, an air bleed bleeder facing the sealing fluid chamber is provided, and the valve seat receives a pressing force from a tightening seal of the air bleed bleeder to control the brake fluid pressure system. A deceleration sensing type hydraulic pressure control device for a vehicle brake system, characterized in that it is configured to be set at a position that partitions a sealing fluid chamber and a sealing fluid chamber.
