The invention relates to a windscreen wiper drive arrangement (1) having a drive shaft (4), extending out of a gear mechanism housing (3), for a windscreen wiper, in which the drive shaft (4) is guided axially through a protective sleeve (15) which is sealed with respect to the drive shaft (4) by means of at least one inner sealing element (18) and with respect to a vehicle component (11) by means of at least one outer sealing element. The invention provides for the protective sleeve (15) to be secured to the gear mechanism housing in order to protect said protective sleeve against axial movement in the direction of the vehicle component (11) and/or against rotational movement relative to the gear mechanism housing (3) by frictional engagement and/or by means of at least one separate securing element (25).
A windscreen wiper drive arrangement comprising a drive shaft (4) guided out of a gear mechanism housing (3) for a windscreen wiper, the drive shaft (4) being axially guided through a protective sleeve (15), which is sealed by at least one internal sealing element (18) relative to the drive shaft (4) and by at least one external sealing element (19) relative to a vehicle component (11), characterized in that the protective sleeve (15) is secured to the gear mechanism housing by at least one securing means securing against an axial movement in the direction of the vehicle component (11) and a rotational movement of the protective sleeve (15) relative to the gear mechanism housing (3), characterized in that the protective sleeve (15) includes a conically widened end region (16) and the gear mechanism housing (3) includes a conically tapered fixing dome (10), and characterized in that the securing means includes an engagement between the conically widened end region (16) and the conically tapered fixing dome (10).
