Abstract:

The objective of the present invention is to provide a dust cover for a ball joint which has good sealing performance at a small-diameter opening at the other end, and with which co-rotation of a plate member can be reliably prevented. In this dust cover for a ball joint, one end of a ball stud is held in a socket and the other end is secured by tightening, by means of a tightening means, a knuckle equipped with a notch part, a large-diameter opening at one end is affixed to and held on the socket side, a small-diameter opening on the other end is held on a shaft, and a plate member is held between the outer circumferential surface of the shaft and the inner circumferential surface of the knuckle on the small-diameter opening on the other end. This dust cover is configured such that the plate member is provided with an annular plate member, an annular seal part manufactured from a rubber-like elastic material and integrally formed on the inner circumferential side of the annular plate member, and an engaging protrusion that is manufactured from a rubber-like elastic material and engages the notch part on the knuckle-side surface of the annular plate member, with the annular seal part being compressed and held between the outer circumferential surface of the shaft and an annular step part provided on the inner circumferential surface of the knuckle.
