にしたことを特徴とするダストカバー。[Claims for Utility Model Registration] One end has a stud fitting part that fits into a ball stud, the other end has a socket fitting part which fits into a ball joint socket, and a substantially cylindrical boot part in the center. In the dust cover having a dust cover main body having a valve member attached to a boot portion thereof, an atmosphere conduction hole is formed in the boot portion and a region around the atmosphere conduction hole is raised outward to form a raised portion; a shaft portion slidably arranged to penetrate the valve member through the atmosphere conduction hole; an engaging portion provided at an inner end of the shaft portion and removable from a peripheral area of the atmosphere conduction hole on the inner surface of the boot portion; a cover member is provided on the outer end of the shaft portion and is formed with an enveloping piece that surrounds the outer circumferential area of the raised portion, and is provided in the atmosphere communication hole so as to be freely openable and closable, and when the boot portion is under positive pressure, the valve member is 1. A dust cover, wherein the dust cover is pressed to form an atmospheric conduction path between the atmospheric conduction hole, the inner surface of the lid member, and the outer surface of the raised portion.
