  "textContent": "Provided is an electric braking device wherein a friction member is pressed, via a piston driven by an electric motor, against a rotary member that rotates integrally with a vehicle wheel, thus generating a braking force on the vehicle wheel. The electric braking device is provided with: a controller for controlling the electric motor; a rotation angle sensor for detecting a rotation angle of the electric motor; and a return mechanism for applying a return force to a piston in a direction away from the rotary member. Furthermore, the controller executes a proper/improper determination to determine whether the return mechanism is operating properly on the basis of a change in the rotation angle after conduction of electricity to the electric motor is stopped.",
