Abstract
A motor vehicle screen wiper comprises a screen wiper arm having a drive head fastened on an end portion of a motor shaft, which is part of a screen wiper drive unit. The motor shaft end portion comprises a conical portion which is received in a complementary through hole associated with the drive head, and which is extended by a threaded terminal shank on to which a fastening nut is screwed. The radial thrust face of the nut cooperates with a portion, in facing relationship with it, of the upper face of the drive head. The drive head comprises an orientation ring in which the conical through hole is formed, with one face of the orientation ring being formed with a set of ridges which cooperate with a complementary ridged engagement surface formed, in facing relationship with the ridged face of the orientation ring, on the body of the drive head. The body is formed with an oblong through hole through which the end portion of the motor shaft extends.
