STUD BALL, DUST COVER, AND STABILIZER CONNECTING ROD

摘要

Disclosed is a stud ball that can not only increase the assembly production characteristics in a mass-production line, but also can have increased sealing characteristics and be more lightweight. Further disclosed are a dust cover, and a stabilizer connecting rod provided with both. The collar section (111) of the stud ball (110) protrudes outwards in the radial direction of a stud section (210). A cross section of the collar section (111) has a curved section (112) that forms a curved shape from a root section to the outer periphery, and the curved section (112) forms a concave shape with respect to the straight line linking the outer-periphery-side end (112B) and the root-section-side end (112A) of the curved shape. A lip section (122) of the dust cover (121) contacts the collar section (111) and the sealing section (212) of the stud ball (110). A side lip section (123) that forms a shape corresponding to the curved shape of the curved section (112) of the collar section (111) and that contacts the curved section (112) is formed at the end of the lip section (122).
