ABSTRACT:
A wiper arm for driving a wiper blade to wipe a windshield of a vehicle. The wiper arm is composed of an arm head, a retainer, an arm piece and a coil spring for urging the wiper blade against the windshield. The retainer has an inclining front surface to prevent dynamic lift by air flow, and a coil spring is disposed to align with a common longitudinal center line of the retainer and the arm head to prevent an angular moment.
