Beschreibung
Zusammenfassung:	An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin eccentrically connected to the drive shaft, and a driven shaft having a second rotary axis and mounted in the housing for a pivoting movement. The driven shaft is coupled to the drive pin by a gear mechanism converting a rotary motion of the drive shaft into the reciprocating pivoting of the driven shaft. The gear mechanism has first and second transmission stages, the former including a cross slider, and the latter an elastically deformable transmission member. The cross slider has a sliding support extending perpendicular to the first rotary axis and receiving the drive pin. The cross slider is axially guided in the housing to move in an axial direction perpendicular to the first rotary axis and perpendicular to the extension of the sliding support. A link, offset relative to the second rotary axis, connects the cross slider to the elastically deformable transmission member.
