The invention discloses an executor of an electric parking brake system. The executor comprises a shell, a planetary gear system accommodated in the shell, a driving device and at least one gear connected between the planetary gear system and the driving device, wherein the driving device is used for driving the planetary gear system through at least one gear; the planetary gear system comprises multiple stages of planetary gear mechanisms, a gear shell for accommodating the multiple stages of the planetary gear mechanisms and a gear cover connected to one end of the gear shell; the planetary gear system also comprises a central shaft which is positioned at the two ends of the planetary gear system, so the multiple stages of the planetary gear mechanisms rotate around the central shaft; each stage of planetary gear mechanism comprises a sun gear, a plurality of planetary gears engaged with the sun gear and a planetary carrier for supporting the planetary gear. By using the planetary gear system of the novel structure, the executor is convenient to assemble and has higher bearing capacity and better stability. The structure allows that the executor is easier to mount and more convenient and comfortable to use and has higher safety and intelligence.
