Abstract
Provided are a compact, highly reliable electric parking brake driving device and an electric parking brake device. This electric parking brake driving device transmits a driving force generated by an electric motor to a parking brake actuator via a speed reduction mechanism, and makes the wheels generate a braking force. A gear body of the electric parking brake driving device is formed by joining a lower body and an upper body. A bracket member is fixed to the lower body, and the electric motor is positioned in the radial direction by engaging with the bracket member. A rubber disk is placed between the lower end surface of the electric motor and the bottom surface of the lower body, and the rubber disk impels the electric motor toward the bracket member in the direction of the rotation axis.
