An actuator for an electric parking brake system includes a motor, an output member, and a speed reduction device. The speed reduction device includes a transmission mechanism and a self-locking mechanism. The self-locking mechanism includes a fixed member, first and second rotating bodies, and a spring. The second rotating body transmits torque to the output member via a planetary gear mechanism. The spring prevents the brake from driving the motor.
