PURPOSE: A ball joint of a suspension device for a vehicle is provided to prevent the pulling force of minute and main deformation parts from being transmitted to a sealing part of a dust cover in case of deformation caused by the rotation and shaking of a ball stud. CONSTITUTION: A ball joint of a suspension device for a vehicle comprises a case which is fixed to both ends of a stabilizer bar link, a ball stud which is pivotally inserted inside the case, and a dust cover(50) which is installed on an end of the case. The dust cover comprises a sealing part(61) which is coupled to the ball stud, a minute deformation part(71) which is connected to the sealing part, and a main deformation part(81) which has a smaller thickness than the minute deformation part and is connected to the minute deformation part. A holding protrusion(91) and a groove(93) are respectively formed on the inner and the outer connection part of the sealing part and the minute deformation part.
