Abstract
In an electric braking device for a vehicle, the following are carried out in order: a first lock process in which either torque for shifting the ratchet gear in a release direction is generated in an electric motor or the driving of the electric motor is stopped, while a pawl member is being pressed against a ratchet gear; a second lock process in which the rotational angle of the ratchet gear is brought to an angle different from a semi-engaging rotational angle by driving the electric motor; and a third lock process in which the ratchet gear is rotated in the release direction by driving the electric motor in reverse.
