Provided are a clear aligner traction device, clear aligners, and a manufacturing method thereof, by which an orthodontic force may be increased by hanging an elastic belt on the clear aligners in a case when teeth are excessively misaligned and thus incapable of being appropriately aligned using only the clear aligners. The clear aligner traction device may include a button that is integrally formed with a clear aligner body and includes a head having a relatively large width, a neck connected to the head and having a relatively small width, and a connector for connecting the neck to the clear aligner body, and a reinforcer bonded to the button in a shape corresponding to the button to reinforce the strength of the button, such that an elastic member is hooked over the button.
