First Claim
1. A wiper blade of a wiper device for a vehicle windshield including a wiper motor and a wiper arm driven by said wiper motor, said wiper blade comprising:
- a first lever, rotatably connected to said wiper arm, for swinging on said windshield alternately in a first direction and a second direction opposite said first direction;
a second lever extending on a first side of said first lever facing the first direction of swinging of said first lever, said second lever rotatably connected to an end of said first lever on an axis;
a third lever extending on a second side of said first lever facing the second direction of swinging of said first lever, said third lever rotatably connected to the end of said first lever on said axis; and

Abstract
A wiper blade of a wiper device is composed of a primary lever driven by an wiper arm to swing on a windshield, a pair of bowed secondary levers connected to the primary lever to extend on a side of the primary lever facing a direction of the swinging and a pair of bowed yoke levers connected to the primary lever to extend on the side of the primary lever opposite to the secondary levers and a rubber blade supported by the yoke levers. Thus, the primary lever, the secondary levers and the yoke levers are disposed in the same plane above the windshield, thereby reducing the frontal projected area relative to air flow. Each of the secondary levers is connected jointly with one of the yoke levers to rotate on a shaft fixed to the primary lever.
