<p>The invention proposes a motor vehicle windscreen wiper of the type including a windscreen wiper arm, the drive head (18) of which is fixed to an end portion of an output shaft (10) which includes a tapered section (12) which is received in an emerging complementary tapered bore (44) of the drive head (18) and which is extended by an end section (14) onto which is screwed a clamping nut (56), the radial clamping face (58) of which interacts with a portion opposite in the upper face of the drive head (18), characterised in that it includes adjustable means (36, 48) for causing the inclination of the axis of the tapered bore (44) to vary with respect to a reference plane (22) of the drive head, the body (20) of the drive head for example including for this purpose a bore (34), the axis of which is perpendicular to the reference plane (22) and in which there is fitted an adjusting ring (36), the peripheral surface (38) of which is cylindrical and in which the said tapered bore (44) is formed, the axis (Y-Y) of which forms an acute adjusting angle with the axis of the cylindrical peripheral surface of the adjusting ring (36). <IMAGE></p> |
