Abstract
A motor vehicle wiper comprising a driving head designed to be fixed to a free upper end of a wiper driving shaft at a bore includes a wiper arm, which is articulated on the driving head by a rear longitudinal end around a transverse axis which is substantially perpendicular to the general longitudinal direction of the wiper and perpendicular to the driving shaft axis, between a raised position and an operative position toward which it is returned by a helical compression spring inserted between the driving head and a support surface of the arm, the helical compression spring extends around the bore.
