An antiskid control device including a main line system for usual braking operation, a subline system for an antiskid control, and an oil hydraulic mechanism supplying pressurized oil to the subline system. The oil hydraulic mechanism has an oil hydraulic source constantly generating hydraulic pressure during operation of the engine of the vehicle, an oil hydraulic motor driven by the oil hydraulic source, and an oil hydraulic pump discharging a highly pressurized oil. While the oil hydraulic motor is constantly rotated during the operation of the engine, the oil hydraulic pump is rotated when the rotation of the oil hydraulic motor is transmitted thereto. For this purpose, a mechanism for transmitting the rotation between the motor and the pump is provided.
