。[Claims for Utility Model Registration] (1) Closing the gap between a first member and a second member that are arranged concentrically with each other and rotate relative to each other, and It is a conductive sealing member that is electrically conductive, and includes a metal annular support member that is supported and fixed to the first member, and a second member that is supported inside the support member and whose end edge is connected to the second member. A conductive seal consisting of a sealing material made of an elastic material that slides into contact with the surface of the member, and conductive grease that is sealed in a space provided inside the support member and that partially contacts the second member. body. (2) A metal inner ring that is fitted onto the outer peripheral surface of the metal shaft, a metal outer ring provided around the inner ring, an inner ring raceway formed on the outer peripheral surface of the inner ring, and the outer ring. Electrolytic corrosion of rolling bearings for railway vehicles that prevents electrolytic corrosion caused by current flowing through rolling bearings for railway vehicles, which consists of a plurality of rolling elements arranged between the outer ring raceway formed on the inner peripheral surface of the rolling bearing. In the prevention device, the inner peripheral edge of a sealing material made of an elastic material supported inside a metal annular support member that is supported in an electrically conductive state with respect to the outer ring is connected to the inner circumferential edge of the sealing material made of an elastic material. The conductive grease is brought into sliding contact with the outer circumferential surface of a member fixed to the outer circumferential surface of the shaft or the outer circumferential surface of this shaft, and the conductive grease sealed in the space provided inside the support member is applied to the outer circumferential surface of the shaft or the outer circumferential surface of this shaft. A device for preventing electrolytic corrosion of a rolling bearing for a railway vehicle, characterized in that the shaft and the outer ring are electrically connected by contacting the outer circumferential surface of a member made of a conductive material fixed to the outer circumferential surface.
