Windscreen wiper device comprising: - a driveshaft having at least one threading, - an electric motor designed to be able to drive the driveshaft in two directions of rotation about an axis, - a tapped carriage mounted on the driveshaft in such a way as to be driven in translation along the driveshaft under the effect of rotation of the driveshaft about the axis thereof, and having at least one protuberance (61, 62) projecting radially with respect to the axis of the driveshaft, - at least one arm that pivots: • mounted pivotingly about a pivot axis that is orthogonal and spaced apart from the axis of the driveshaft, • comprising a sliding mechanical connection with at least one protuberance (61, 62) of the carriage, said sliding mechanical connection being designed to be able to drive the arm that pivots in rotation about the pivot axis under the effect of a translation of the carriage, • linked in rotation with a windscreen wiper blade, characterised in that: - the carriage is a carriage with recirculating balls designed to cooperate with at least one threading of the driveshaft, - at least one arm that pivots is a fork having at least one forked distal end (41, 42) straddling a protuberance, - each protuberance (61, 62) straddled by a forked end (41, 42) of a fork has a shape designed to be able to be moved in translation between the teeth of the forked end of the fork straddling it, and transform a translation of the carriage in rotation of this fork about the pivot axis, - at least one protuberance (61, 62) comprises a ball bearing mounted with an axis of rotation that is orthogonal to the axis of the driveshaft, with an inner ring of said bearing being immovably fixed to the carriage, and an outer ring rotating freely with respect to the carriage and straddled by a forked end of a fork. - a driveshaft having at least one threading, - an electric motor designed to be able to drive the driveshaft in two directions of rotation about an axis, - a tapped carriage mounted on the driveshaft in such a way as to be driven in translation along the driveshaft under the effect of rotation of the driveshaft about the axis thereof, and having at least one protuberance (61, 62) projecting radially with respect to the axis of the driveshaft, - at least one arm that pivots: • mounted pivotingly about a pivot axis that is orthogonal and spaced apart from the axis of the driveshaft, • comprising a sliding mechanical connection with at least one protuberance (61, 62) of the carriage, said sliding mechanical connection being designed to be able to drive the arm that pivots in rotation about the pivot axis under the effect of a translation of the carriage, • linked in rotation with a windscreen wiper blade, characterised in that: • mounted pivotingly about a pivot axis that is orthogonal and spaced apart from the axis of the driveshaft, • comprising a sliding mechanical connection with at least one protuberance (61, 62) of the carriage, said sliding mechanical connection being designed to be able to drive the arm that pivots in rotation about the pivot axis under the effect of a translation of the carriage, • linked in rotation with a windscreen wiper blade, characterised in that: - the carriage is a carriage with recirculating balls designed to cooperate with at least one threading of the driveshaft, - at least one arm that pivots is a fork having at least one forked distal end (41, 42) straddling a protuberance, - each protuberance (61, 62) straddled by a forked end (41, 42) of a fork has a shape designed to be able to be moved in translation between the teeth of the forked end of the fork straddling it, and transform a translation of the carriage in rotation of this fork about the pivot axis, - at least one protuberance (61, 62) comprises a ball bearing mounted with an axis of rotation that is orthogonal to the axis of the driveshaft, with an inner ring of said bearing being immovably fixed to the carriage, and an outer ring rotating freely with respect to the carriage and straddled by a forked end of a fork.
