Sealing device and drive unit with 2-component sealing device

The invention relates to a sealing device for a passage seal on a drive unit. When a housing is abutted against a bearing member in a pass-through port area of the bearing member via the sealing device assembled to an interface section, the housing is sealed on the interface section to be connected with an electric connection piece on a drive unit casing, the electric connection piece extends through the pass-through port. The sealing device has a sealing element formed by an elastic material and used to be hermetically abutted against the edge of the pass-through port of the bearing member, and a fastener formed by a material harder than the material of the sealing element and used for fixing the sealing device to the interface section. The sealing element has a first connection section and the fastener has a second connection section. The sealing element and the fastener are fixed to each other on the first and second connection section. The first connection section of the sealing element and the second con
