Abstract: A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.

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.

Abstract: A vehicle wiper device including (i) a first motor that includes a first output shaft, that rotates the first output shaft to rotate a wiper arm back and forth about a pivot point of the wiper arm, and that causes a wiper blade coupled to a leading end portion of the wiper arm to perform a back and forth wiping operation between an upper return position and a lower return position on a windshield, (ii) a second motor that changes a wiping range on the windshield by the wiper blade, (iii) a rotation angle detector that detects a rotation angle of the first output shaft, and (iv) a controller that controls the second motor according to a rotation angle of the first output shaft detected by the rotation angle detector in a state in which a broad field of view should be secured on a front passenger seat side.
