ABSTRACT:
A wiper arm is provided with a resinous intermediate member between a retainer made from an iron-based alloy and an arm head die cast from an aluminum alloy. The wiper arm is free from electrochemical corrosion because the retainer and the arm head are not in contact with each other due to said resinous intermediate member disposed therebetween.
