摘要： A brake force control device for a vehicle includes a master cylinder for being operated by an operating member of the vehicle, a wheel brake for being mounted on a vehicle wheel which is connected to the master cylinder through a conduit, a pressure control chamber connected to the wheel brake, a displacement actuator which varies a capacity of the pressure control chamber and a control unit which controls the displacement actuator. The displacement actuator includes a plunger which varies a capacity of the pressure control chamber, a drive unit which drives the plunger, a first valve which closes the conduit when the plunger is operated to decrease the capacity of the pressure control chamber and which opens the conduit when the first valve receives a brake pressure from the master cylinder which is larger than that in the pressure control chamber with a predetermined value, and a second valve which closes the conduit when the plunger is operated to increase the capacity of the pressure control chamber and which opens the conduit when the brake pressure in the pressure control chamber is larger than that in the master cylinder with a predetermined value.
