    摘要: The invention relates to a wiper motor (10) with a shaft (30) for driving a wiper arm (1 ), wherein the shaft (30) projects through an opening (31 ) of a housing (15) and in the region of the opening (31 ) is mounted radially in a bore (55) of at least one substantially sleeve-shaped element (40), and wherein the sleeve-shaped element (40) is fixed at least axially in the region of the housing (15). According to the invention, it is provided that the sleeve-shaped element (40) has at least two different cross-sections (41, 42), a first cross-section (41 ) which is designed to protrude axially through the opening (31 ) and a second cross-section (42) which is designed to be accommodated in an axially fixed manner within said opening (31 ).

    摘要: The invention relates to a drive apparatus (1) for operating an element in a motor vehicle, in particular a wiper arm, having a housing (2), an electric motor, a gear wheel (4) which can be driven in a rotatable manner by the electric motor, having a switching disc (6) which is arranged on the gear wheel (4) and having at least one sensing finger (7), which makes contact with the switching disc (6) as a sliding contact, for generating a position-dependent electrical signal. According to the invention, provision is made for damping means (13) which are composed of a vibration-damping material for acoustically decoupling the sensing finger (7) to be assigned to the sensing finger (7). The invention also relates to a window wiper apparatus.
