WIPER ARM AND METHOD OF MANUFACTURING SAME

The present invention improves wiping performance and design while reducing size and weight. A driver-side wiper arm 120 is constituted by an arm head 130, an arm shank 140, and an arm piece 150, and thus a percentage of the longitudinal direction of the driver-side wiper arm 120 occupied by the arm shank 140 can be reduced. In other words, because the arm piece 150 is provided, the arm shank 140 can be shortened. This makes it possible to make the entire driver-side wiper arm 120 smaller and lighter, as well as improve wiping performance. Additionally, a cover member 170 is attached to a part of the arm piece 150, a washer tube TB, which is disposed at that part, can be hidden. The design of the driver-side wiper arm 120 can therefore be improved.
