PURPOSE: A combining structure of ball stud of a gas spring is provided to make possible recycling of a stud bolt in the replacement of a gas spring by making a stud bolt easily separated from a steel body and to reduce the cost for the replacement of a gas spring. CONSTITUTION: A clip(1) is firmly combined to a steel body(2) by inserting a rear protruded piece formed on the rear of the clip to a protruded piece insertion groove(31) and inserting two lower protruded pieces(15) formed on the front end of the clip to another protruded piece insertion groove(22). A spherical head part of a ball stud is inserted via an insertion groove(13). The head part is not separated from the steel body according to the contraction by releasing widened state of the front end of the clip. When a gas spring needs to be replaced due to aging, a tool clamp hole(14) formed on the upper of the front end of the clip is widened by using a sharp tool such as a nipper. The spherical head part is separated from the ball stud. Thereby the aged gas spring is replaced.
