Abstract
The invention comprises a bearing arrangement for a rotating shaft in a windshield wiper driving mechanism, of the kind comprising a housing having a bore through which the shaft passes and including a bearing sleeve which comprises at least an inner radial flange, a first face of which forms a first shoulder for the axial positioning of a seal provided in the bore which cooperates with the opposite cylindrical surfaces of the bore and of the shaft. According to the invention, one of the ends of the bearing sleeve abuts against a second shoulder formed by the second face of the radial flange, and the internal diameter of the inner radial flange is greater than the internal diameter of the bearing sleeve.
