レーキ装置。 In an anti-skid brake system installed in a four-wheel drive vehicle in which the front wheels and rear wheels are connected to each other with a rotational restraint force, a master brake system is used to connect the front and rear brake cylinders of the respective brake cylinders of the wheels. Two sets of independent hydraulic piping to which the hydraulic pressure of the cylinders is supplied, a modulator installed in the middle of one of the two sets of hydraulic pipes to perform an anti-skid operation, and an interconnection between the two sets of hydraulic pipes. A hydraulic pressure difference reducing means is installed between the two hydraulic pipes to reduce the hydraulic pressure difference between the two hydraulic pipes, and a hydraulic pressure difference reducing means is provided between the two hydraulic pipes to reduce the hydraulic pressure difference between the two hydraulic pipes. 1. An anti-skid brake device characterized by comprising a one-way throttling means for reducing the brake fluid pressure of the rear wheels and directing only the return direction of the hydraulic pressure from the rear wheels in a normal state.
