    • PROBLEM TO BE SOLVED: To provide a vehicle braking device capable of reducing cost while achieving a further proper pressure adjustment. SOLUTION: This vehicle braking device 1 includes a master cylinder 2 for generating operational hydraulic pressure from basic hydraulic pressure in response to operation of a pedal, a pump 3 for boosting the operational hydraulic pressure, a pressure adjusting valve 4 for generating control hydraulic pressure by adjusting the boosted operational hydraulic pressure, supply means 6 and 7 for supplying the operational hydraulic pressure or the control hydraulic pressure to a wheel cylinder 5 as supply hydraulic pressure, and a control means 10a for controlling the control hydraulic pressure in target control hydraulic pressure by controlling a closing unit time TC by setting an opening unit time of the pressure adjusting valve 4 to a variation period TQ of a deliver flow rate of the pump 3.
