The windscreen wiper mechanism has a pivot (36) between the wiper arm (16) and the drive crank (10,12). The pivot assembly (20) has a flat head (22) that presses against part of a support surface on the outer lateral face (34) of the crank. The main part of the pivot is a cylindrical pin (24) of slightly smaller diameter than the head, and the end part of the pin is a cylinder of smaller diameter (28) than the main part. The main part of the pin runs in a bushing (26) in a hole in the crank arm. The smaller part of the pin runs in a smaller diameter hole (18) formed in the wiper arm. A flattened head (30) at the end of the smaller diameter part of the pin rests on the outer face (54) of the wiper arm. The two heads clamp the two parts together. <IMAGE> |
