The present invention relates to a ball joint which is used in a step link or a step bar which is combined with a strut which forms a front wheel suspension of a vehicle and, more specifically, to a ball joint structure which prevents the entering of foreign substances and a noise generation while increasing the pitch angle of a ball stud. More specifically, the ball joint structure of a step link, provided by the present invention, includes: a ball stud (10) which includes a globular head part (11); a bearing (20) which is formed to be dented in a globular shape which corresponds to the head part (11) in one side; an internal case (30) which covers the lateral and rear sides of the bearing (20); an external case (40) which supports the lateral side of the internal case (30); a bush (35) which is formed between the internal case (30) and the external case (40); and a dust cover (50) which prevents the entering of foreign substances by being formed along a combining surface between the ball stud (10) and the bearing (20). |
