Provided are a compact, highly reliable electric parking brake driving device and an electric parking brake device. This electric parking brake driving device (3) transmits a driving force generated by an electric motor (34) to a parking brake actuator via a speed reduction mechanism (R), and makes the wheels generate a braking force. A gear body (31) of the electric parking brake driving device (3) is formed by joining a lower body (32) and an upper body (33). A bracket member (35) is fixed to the lower body (32), and the electric motor (34) is positioned in the radial direction by engaging with the bracket member (35). A rubber disk (36) is placed between the lower end surface (34a6) of the electric motor (34) and the bottom surface (32d) of the lower body (32), and the rubber disk (36) impels the electric motor (34) toward the bracket member (35) in the direction of the rotation axis (ψ). |
