When a wheel speed is recovered by means of a road surface reaction force, the liquid pressure is fed to the brake device for repressurization. In this case, the pedaling force of the brake pedal is detected. Variable control is made so that, with the increase in a detected pedaling force, a set value of a slip ratio in which the liquid pressure in the brake device for each wheel is reduced is gradually increased. This constitution freely selects control, in which priority is given to a brake force and a side force, according to the magnitude of a pedaling force.
