Abstract
A windscreen wiper arm, particularly for automobiles, includes a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin. The arm member has a substantially U-shaped cross-section near the pivot pin comprising two side walls. A part of the mounting head extends between the side walls and beyond the pivot pin. The part is provided with opposite surfaces each facing towards a respective side wall of the arm member. Each surface of the part of the mounting head is positioned spaced-apart from its respective side wall of the arm member, so as to allow paint to enter a space defined between each surface of the part of the mounting head and its respective side wall of the arm member.
