An objective of the present invention is to provide a sealing device in which occurrence of rusting on the axial end face of a housing such as the outer race or the like, to which the sealing device is fitted, is effectively suppressed and thereby deterioration of a fixedly fitted part and the slide movement wear of a seal lip due to rust can be prevented. The sealing device comprises an end face rust-preventive seal part 9 to prevent the adhesion of moisture as external foreign matters to an axial end face 21a of a housing 21 such as an outer race or the like of a bearing, so as to prevent occurrence of rusting on the axial end face 21a. The end face rust-preventive seal part 9 seals moisture by covering the axial end face 21a of the housing 21 by its component, or by extending the component in a hood shape on the outer peripheral side of the axial end face 21a of the housing 21.
