A windshield wiper arm is formed of a single metal blank bent to different cross sectional configurations along its length to strengthen and reinforce it, and including a long substantially tubular portion intermediate its ends. A windshield washer nozzle is mounted at the free end of the arm and is supplied by an elongated liquid tube concealed and protected within the arm by the tubular portion of the arm and by the coil spring urging the arm toward the windshield. |
