Geared motor, for driving the arms of a motor-vehicle windscreen wiper, comprising: - a drive shaft, - a driven shaft, - a gear transmission between the drive shaft and the driven shaft, comprising: ∘ a first worm screw that is as one with the drive shaft, ∘ a first intermediate pinion having a first and a second toothing (20a, 20b), the first toothing of the first intermediate pinion meshing with the first worm screw, ∘ a driven wheel that is as one with the driven shaft, having an output toothing meshing with the second toothing of the first intermediate pinion, in which the output toothing of the driven wheel and the second toothing of the first intermediate pinion are formed such that two opposite flanks (42a, 42b) of a tooth of the output toothing of the driven wheel meshing with the second toothing of the first intermediate pinion are in contact with the second toothing of the first intermediate pinion, characterized in that said tooth of the output toothing of the driven wheel is in contact with the second toothing of the first intermediate pinion at two axially offset locations (C1, C2), and in that a toothing play is maintained opposite the contact (C1, C2), between the flank (42a, 42b) of the tooth of the output toothing of the driven wheel and the second toothing of the first intermediate pinion. - a drive shaft, - a driven shaft, - a gear transmission between the drive shaft and the driven shaft, comprising: ∘ a first worm screw that is as one with the drive shaft, ∘ a first intermediate pinion having a first and a second toothing (20a, 20b), the first toothing of the first intermediate pinion meshing with the first worm screw, ∘ a driven wheel that is as one with the driven shaft, having an output toothing meshing with the second toothing of the first intermediate pinion, in which the output toothing of the driven wheel and the second toothing of the first intermediate pinion are formed such that two opposite flanks (42a, 42b) of a tooth of the output toothing of the driven wheel meshing with the second toothing of the first intermediate pinion are in contact with the second toothing of the first intermediate pinion, characterized in that said tooth of the output toothing of the driven wheel is in contact with the second toothing of the first intermediate pinion at two axially offset locations (C1, C2), and in that a toothing play is maintained opposite the contact (C1, C2), between the flank (42a, 42b) of the tooth of the output toothing of the driven wheel and the second toothing of the first intermediate pinion. ∘ a first worm screw that is as one with the drive shaft, ∘ a first intermediate pinion having a first and a second toothing (20a, 20b), the first toothing of the first intermediate pinion meshing with the first worm screw, ∘ a driven wheel that is as one with the driven shaft, having an output toothing meshing with the second toothing of the first intermediate pinion, in which the output toothing of the driven wheel and the second toothing of the first intermediate pinion are formed such that two opposite flanks (42a, 42b) of a tooth of the output toothing of the driven wheel meshing with the second toothing of the first intermediate pinion are in contact with the second toothing of the first intermediate pinion, characterized in that said tooth of the output toothing of the driven wheel is in contact with the second toothing of the first intermediate pinion at two axially offset locations (C1, C2), and in that a toothing play is maintained opposite the contact (C1, C2), between the flank (42a, 42b) of the tooth of the output toothing of the driven wheel and the second toothing of the first intermediate pinion.
