ABSTRACT:
A motorised reduction gear unit, especially for a vehicle screen wiping system, comprises a hollow casing closed by a cover plate, and, within the casing, a toothed wheel which is rotatable about an axis and which carries a pin parallel to the toothed wheel axis and eccentric with respect to the axis. This pin drives a crank and connecting rod unit to convert continuous rotation of the toothed wheel into an alternating motion of an output shaft. The output shaft is provided with braking means for applying braking action to its rotation.
