Claims

[Scope of utility model registration request]

A hydraulic pressure control valve that 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 that moves and comes into contact with the valve seat when the vehicle braking exceeds a certain value. A vehicle brake system comprising: an inertia valve that seals a sealing fluid chamber communicating with the brake fluid pressure system and varies a corner value of the pressure reduction control in proportion to the value of the sealed fluid pressure. In the deceleration sensing type hydraulic pressure control device, - the sealing liquid chamber following the valve seat has a loosening valve for detecting movement in the axial direction of the valve seat;
A bleeder bolt for air venting is provided to communicate and cut off the fluid chamber and the outside during tightening operation, and the end of this bleeder bolt protrudes from the valve seat toward the inertial ball when loosened. A deceleration sensitivity sensing type hydraulic pressure control device for a vehicle brake system, characterized in that it is configured to lock the abutment against a valve seat.
