。[Scope of Claim for Utility Model Registration] (1) A master cylinder equipped with a valve piston whose rear end protrudes from the valve body, and which is installed in a fluid passage connecting a master cylinder and a rear brake cylinder of an automobile hydraulic brake system. A proportioning valve that reduces hydraulic pressure and transmits it to the rear brake cylinder, a load member that displaces in the axial direction of the valve piston as the rear wheel load changes, and a proportioning valve that reduces hydraulic pressure and transmits it to the rear brake cylinder; a rear wheel load detection mechanism having a load detection spring that applies a biasing force in a positive direction and applies a biasing force in a negative direction when the rear wheel load is small; A brake fluid pressure control device for an automobile, comprising: a negative direction force transmitting member that abuts from the side and receives the negative biasing force of the load detection spring and transmits it to the valve piston. (2) The negative direction force transmission member is movable relative to the valve piston in the axial direction, and is biased toward the load member by an elastic member provided between the valve piston and the valve piston. ,
A utility model registration claim in which the load characteristics of the elastic member are determined such that a negative biasing force applied from the load detection spring to the load member is transmitted to the valve piston with elastic deformation of the elastic member. The automotive brake fluid pressure control device according to item 1.
