The invention relates to a cervical traction therapy apparatus comprising a footstock, a neck ring, a hauling rope unit and a retractor. The hauling rope unit is arranged between the footstock and the neck ring for connection. The hauling rope unit is used for connecting the footstock with the hauling rope unit and leads the neck ring to the particular position where the neck ring is arranged under the footstock. One end of the hauling rope unit is connected with the neck ring and the stressed included angle of the hauling rope unit corresponding to the footstock can be changed, thus achieving the purpose of changing the direction and the angle of the neck ring by coordinating with the hauling rope unit. Therefore, the cervical traction therapy apparatus is designed to provide function ofadjusting the hauling direction and the angle of traction.
