Plain bearing or rolling bearing equipped with a sealing device with a seal seat close to the axis of revolution

A motor vehicle wheel support device, comprising a plain bearing or rolling bearing, the plain bearing or roller bearing comprising at least one inner ring and at least one outer ring, the inner ring and the outer ring being able to rotate relative to one another about an axis of revolution of the bearing, the inner ring having a guide race, the outer ring having at least one guide race located opposite the guide race of the inner ring and delimiting with the guide race of the inner ring an inner volume of the bearing, the inner ring having an axial end face facing a reference axial direction{circumflex over ( )} parallel to the axis of revolution, the axial end face being located axially at a distance from the guide race of the inner ring in the reference direction, the inner ring having a shrink-fitting bearing surface located axially between the axial end face and the guide race of the inner ring, the bearing including a sealing device, the sealing device including at least an outer structure secured to the outer ring and an inner structure secured to the inner ring, the outer structure and the inner structure together delimiting a sealing volume open on the inner volume of the bearing, the inner structure including a shrink-fitted portion shrink fitted onto the shrink-fitting bearing surface of the inner ring and at least one seal seat, the outer structure including at least one seal lip in sliding contact against the seal seat, the seal seat and the seal lip sealing the sealing volume, the seal seat being located axially at a distance from the axial end face of the inner ring in the reference axial direction, and being closer to the axis of revolution than the shrink-fitting bearing surface, wherein

• the seal seat faces radially away from the axis of revolution of the bearing:
• the inner structure further includes a connecting portion protruding axially relative to the seal seat in the reference direction, and a deflector protruding radially from the connecting portion in a radial direction facing away from the axis of revolution;
• and
• the deflector forms with the outer structure a chicane passage opening into the sealing volume, the chicane passage having an inlet further from the axis of revolution than the seal seat, the seal seat and the seal lip being positioned in the sealing volume and interposed between the chicane passage and the inner volume of the bearing, wherein, the inner ring is a rotating ring, and the outer ring is a fixed ring having an interface for fastening to a wheel support.
