PURPOSE: Coupling structure for a pitman arm is provided to improve working efficiency by coupling conveniently with obtaining the gap between the pitman arm and parts, and to lengthen the life span by increasing the strength of the coupling part. CONSTITUTION: A ball joint(10) is composed of a coupling part(11) combined with a hole(5) of a pitman arm(4), and a ball stud(12) combined with a drag link. A sill part(13) is formed in the lower part of the ball stud of the ball joint, and the end of the coupling part is protruded in the hole of the pitman arm. The strength of the coupling part is improved by fixing the end of the coupling part with welding. The position of the coupling part is adjusted easily with forming the sill part between the ball stud and the coupling part.
