BRAKING DEVICE FOR VEHICLE

A vehicle braking device includes: an electric cylinder in which a piston driven by an electric motor slides in a cylinder to supply fluid; a hydraulic pressure output unit connected to the electric cylinder by way of a first liquid passage, the hydraulic pressure output unit pressurizing or depressurizing a hydraulic pressure in the first liquid passage and outputting the hydraulic pressure to a supply liquid passage connected to a first wheel cylinder; and a control unit that causes at least one of the electric cylinder and the hydraulic pressure output unit to generate the hydraulic pressure in the first wheel cylinder according to a relative position between the piston and the cylinder.
