Claims

[Claims for Utility Model Registration] (1) A first piston that is slidably housed in a housing and is divided into an inflow chamber that communicates with a hydraulic pressure generation source and an outflow chamber that communicates with a brake cylinder; and the first piston. a second piston that penetrates through the inflow chamber and has a small diameter pressure receiving part on the inflow chamber side and a large diameter valve part on the outflow chamber side; and a second piston that is contracted in the outflow chamber and urges the first piston toward the inflow chamber. a second spring that is compressed between the bottom of the housing in the inflow chamber and the second piston and urges the second piston toward the outflow chamber; and a second spring that interrupts the supply of hydraulic pressure from the inflow chamber to the outflow chamber. A brake fluid pressure control valve comprising: a valve mechanism configured such that the load of the second spring acts only on the second piston. (2) A difference in which the inflow chamber that is slidably fitted into a stepped hole in the housing and communicates with the hydraulic pressure generation source is divided into a small diameter chamber, and the inflow chamber that communicates with the brake cylinder is divided into a large diameter chamber. a second piston that passes through the first piston and has a small-diameter pressure receiving part on the inflow chamber side and a large-diameter valve part on the outflow chamber side; The second spring is compressed between the piston and the second piston and urges the second piston toward the outflow chamber, and the valve mechanism is configured to cut off and cut off the supply of hydraulic pressure from the inflow chamber to the outflow chamber, and the load of the second spring is A brake fluid pressure control valve configured to act only on the second piston.
