Abstract
The screen wiper mechanism has a crank, a connecting rod, a pivot pin and an articulating device which couples the crank to the connecting rod. The structure has, in succession: a head which bears against an engagement surface that is formed, in facing relationship with the head, in a first lateral face of the connecting rod. A cylindrical first shank portion and a cylindrical second shank portion that is of smaller diameter than the first shank portion forms an extension to the first shank. The articulating device also has structure that secures the crank on the second shank portion of the pivot pin against relative axial movement and takes up axial clearance. This structure, moreover, is arranged to be compressed while fastening the structure together during assembly.
