PROBLEM TO BE SOLVED: To provide a dust cover capable of preventing the abnormal sound accompanied by the expansion and contraction of bellows from being made. SOLUTION: The dust cover which is made of a cylindrical elastic body and in the shape of bellows having a plurality of top parts 11 becoming convex outwards in the radial direction and a plurality of bottom parts 12 becoming concave outwards in the radial direction, and the dust cover provides a clearance forming means preventing the adjoining top parts 11A, 11B themselves or adjoining bottom parts 12A, 12B themselves or both of then from touching in the state where the bellows are contracted. The clearance forming means is, for example, a projection 13 installed in the top part 11 and the bottom parts 12.
