The present invention relates to a ball joint structure and a manufacturing method thereof, which can simplify a manufacturing process, can reduce a weight thereof, and can secure durability thereof, simultaneously. The ball joint structure according to an exemplary embodiment of the present invention includes: a ball stud having a ball formed at one end thereof; a bearing including a first bearing coupled to the ball for an interior surface thereof to slide on an exterior surface of the ball and covering an exterior surface of one side of the ball, and a second bearing coupled to the ball for an interior surface thereof to slide on the exterior surface of the ball and covering an exterior surface of the other side of the ball; and a ball housing which is insert-molded together with the bearing to cover the outside of the bearing. Accordingly, the present invention improves assembly availability by separately mounting the first bearing and the second bearing on the ball formed at the ball stud, and prevents permeation of resin by forming stepped parts between the first bearing and the second bearing when the ball housing is insert-molded. |
