Zusammenfassung:	In the present invention, a parking brake actuator generates braking force at vehicle wheels by means of converting the rotary motion of a screw member rotated by this electric parking brake driving device to linear motion, transmitting the result to a piston, and pressing a brake pad against a disc rotor by means of the piston. The electric parking brake driving device is provided with an electric motor and a speed reduction mechanism that transmits the driving force of the electric motor to the parking brake actuator. The speed reduction mechanism is provided with a gear body and a planetary gear mechanism provided within the gear body and to which the driving force of the electric motor is input. A cushion rubber that can be compressed in the circumferential direction is interposed between the gear body and the ring gear of the planetary gear mechanism.
