  • Publication number: 20040187247
    Abstract: A cover of a wiper blade for a vehicle includes a front surface wall and a rear surface wall, which are connected to each other to form a cap-shaped elongated body that has a base end opening at a base end thereof and that receives primary and yoke levers and backing plates, which are connected to a blade rubber. The front surface wall has a tilted outer surface that is tilted relative to a wiping surface to form a fin, which limits lifting of the wiper blade from the wiping surface when the vehicle is running.

  • Patent number: 5186064
    Abstract: A wiper is provided for use in a vehicle for wiping the windshield glass. A holder is fixed to a baseplate of the vehicle body and, against the holder, an inner bearing is supported so as to rotate about its axis. A pivot shaft is inclined relative to the axis of the inner bearing while being rotatably supported. The driving force is transmitted from a driving source into driving forces for a first driving apparatus for driving the pivot shaft and second driving apparatus for driving the inner bearing. Inversion apparatus or a rotating apparatus always rotates the second driving apparatus either in a direction opposite to or in the same direction as the rotational direction of the first driving apparatus.
