Abstract
An object of the invention is to provide a dust cover for a ball joint which can suppress generation of a so-called mouth opening phenomenon in a small-diameter opening portion even under a low-temperature atmosphere, can effectively inhibit a seal performance from being lowered in the small-diameter opening portion and inhibit the sedimentation or the garbage from entering into a dust cover from an external portion, and has a good sealing performance. For this purpose, in a dust cover for a ball joint having a spherical head portion, a shaft, one end large-diameter opening portion, the other end small-diameter portion, and a film portion, concavo-concave engagement is formed between an inner peripheral surface of the rigid ring and an outer peripheral surface of a retainer having a cylindrical portion which is fitted and retained to an outer peripheral surface of the shaft.
