する車両用ブレーキ装置。[Claim for Utility Model Registration] A fluid pressure brake device that suppresses wheel rotation by supplying fluid pressure to the left brake cylinder of the brake installed on the left wheel and the right brake cylinder of the brake installed on the right wheel, respectively. and a brake cylinder pressure control device that independently controls the pressure in the left brake cylinder and the pressure in the right brake cylinder, wherein the pressure in the left brake cylinder and the pressure in the right brake cylinder are controlled independently. differential pressure limiting means for controlling the pressure of the uncontrolled brake cylinder to prevent the pressure difference between the two brake cylinders from increasing beyond a set value when one of the brake cylinders is controlled by the brake cylinder pressure control device. A vehicle brake device characterized by being provided with a vehicle brake device.
