Abstract

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).
