Windscreen wiper device with drive head to shaft connection

摘要

The invention proposes a windscreen wiper of the type comprising a rotating motor shaft (12) and a driving head (10) on which a windscreen wiper arm is articulated, and of the type comprising coupling means between the driving head (10) and the free end (28) of the motor shaft (12), which is mounted in a seat (22, 24) formed in the driving head (10), which comprise rotational coupling means by cooperation of shapes (42) and axial clamping means (38) comprising a unit of the screw-nut type, characterized in that the rotational coupling means by cooperation of shapes comprise a series of teeth (42) associated with the motor shaft (12), angularly distributed in a regular manner around the axis (X-X) of the motor shaft (12) and angularly spaced in relation to one another and which cooperate with an associated bearing surface (23) formed in the driving head (10).
