PROBLEM TO BE SOLVED: To suppress the occurrence of vibration of braking force due to operation lag of a brake actuator used in an ABS control. SOLUTION: An ABS device is equipped with a brake friction coefficient threshold value setting part 32 which detects the brake friction coefficient at the time when the brake friction coefficient is turned from the increase trend to the decrease trend during the increase of slip ratio, and an ABS control part 33 which controls the brake liquid pressure so that the brake friction coefficient in controlling the brake liquid pressure is in the range set within the brake friction coefficient detected by the brake friction coefficient threshold value setting part 32 in the area of the slip ratio smaller than that corresponding to the brake friction coefficient at that time when the brake friction coefficient setting part 32 detects the change of the trend.
