Claims

[Scope of utility model registration request]

The housing has an inlet that communicates with the master cylinder, an outlet that communicates with the master cylinder, and an inner hole that communicates with the inlet and the outlet. Communication between...a valve seat with a valve hole provided at its mouth, and a valve seat that is accommodated within the inner corner and moves upon sensing deceleration to the valve seat! a bypass inner hole provided in the how ring and communicating with the upper inner wall of the inner hole and communicating with the outlet; and a bypass inner hole interposed in the six-pass inner hole. In a deceleration sensing type braking hydraulic pressure control device comprising a shut valve, the bypass inner hole is closed by a force that closes the bypass inner hole when the hydraulic pressure in the bypass inner hole is equal to or higher than a set value. (A deceleration-sensing brake hydraulic pressure control device characterized by having an orifice with a passage area smaller than the minimum passage area of the inner hole.
