PURPOSE:To improve the workability of bleeding air from a power hydraulic system by separately mounting a reservoir and a hydraulic pump on a vehicle, from a cut valve, a pressure regulating valve, etc. which are installed to a body. CONSTITUTION:Sensors 31 to 34 for detecting the number of revolutions of right and left and front and rear wheels, a computer 40, and an actuator A are provided in an antiskid device. The reservoir 51 of an actuator A stores the same fluid as the brake fluid in a brake hydraulic circuit from a master cylinder 12 to each of wheel cylinders 21 to 24, as a hydraulic medium for power. And, by separately mounting the reservoir 51 and a hydraulic pump 52 on a vehicle, from an assembled body consisting of a pressure regulating valve 56, cut-valve piston parts 58A to 58D, solenoid valves 57A to 57C, bypass valves 59A to 59D, etc. which are installed to a body 50, the workability of bleeding air from a power hydraulic system can be remarkably improved.
