Wiper arm for motor vehicle's windscreen wiper system

摘要

The wiper arm is attached to a drive shaft (8) by an attachment element located in an opening in the wiper arm. The wiper arm's attachment element, which may be a nut (10) or screw, is retained on a part of the arm. If the element is a nut, it is clipped into a simple nut cap (13) which is retained by a flexible connecting element (15) on the wiper arm. The nut may be fitted by means of a groove in an elastic holder which is also retained by a flexible element on the wiper arm.
