BALL STUD, DUST COVER, AND STABILIZER LINK

A ball stud, a dust cover, and a stabilizer link with them, in which the sealing characteristics are improved and the weights thereof are reduced, while assembling productivity in a mass production line is improved, are provided. A ball stud 110 has a flange 111 that outwardly projects in a radial direction of a stud portion 210. The flange 111 has a concave portion 112 that has a curved shape from a root to an outer circumferential portion in cross section. The concave portion 112 is concave with respect to a straight line connecting an end 112A on the root side and an end 112B on the outer circumferential portion side of the curved shape. A dust cover 121 has a lip 122 to be abutted on a sealing portion 212 and the flange 111 of the ball stud 110. The lip 122 has a circumferential end that is formed with a side lip portion 123. The side lip portion 123 has a shape corresponding to the curved shape of the concave portion 112 of the flange 111 so as to be abutted on the concave portion 112.
