ABSTRACT:
According to an embodiment of the present invention, there is provided an EPB serving as an electrical parking brake in which a gear wheel and an external ring gear are arranged parallel to a driving gear rotating through a motor serving as the power source on a side surface, and fixed and output sun gears generating output torque are arranged to penetrate the external ring gear in a shaft direction via an internal ring gear and a planetary gear being in inner contact with the external ring gear, an overall length of a single body type housing with the motor is determined only by diameters of the driving gear, the gear wheel, and the external ring gear. Therefore, a power assembly converting the power of the motor driven by an ECU into the output torque is downsized so that a caliper mounted on a wheel presses a wheel disk.
