Abstract: A vehicle wiper device includes a first driving lever, a second driving lever, a first driven lever, a second driven lever, a first wiper arm, a first wiper blade, a second wiper arm, and a second wiper blade. The first driving lever is pivoted by a driving force of a first drive source. The second driving lever is pivoted by a driving force of a second drive source. A pivoting speed of the second wiper blade from a lower reversal position is set to be greater than a pivoting speed of the first wiper blade from a lower reversal position.

Abstract: A first driven lever of a vehicle wiper device has a proximal end pivotally connected to a distal end of a first driving lever. A second driven lever has a proximal end pivotally connected to a distal end of the first driven lever and a distal end pivotally connected to a distal end of a second driving lever. A first wiper arm operates integrally with the second driven lever and has a distal end to which a first wiper blade is connected. A swing transmission mechanism transmits a driving force to the first driving lever. The swing transmission mechanism includes a swing crank arm integrally rotatable with a rotation shaft of a single drive source. An extension-contraction transmission mechanism transmits a driving force to the second driving lever. The extension-contraction transmission mechanism includes an extension-contraction crank arm integrally rotatable with the rotation shaft of the drive source.
