Abstract
A screen washing apparatus, especially for a glass surface of a motor vehicle, in which a shaft is formed with a through duct and is carried by the casing of a motorized reduction gear unit. The reduction gear unit drives the screen wiper and imparts to the shaft an alternating rotary motion through a drive element. An end portion of the shaft penetrates sealingly into a bore that is formed in a tubular connector. The tubular connector joins the apparatus to a flexible pipe leading from a screen washing liquid supply circuit. The tubular connector and the end portion of the shaft are coupled together in rotation by a mating coupling, and the shaft has, at its end penetrating into the tubular connector, a knurled surface and a spherical portion, the spherical portion deforming the bore of the tubular connector radially outwardly.
