Vehicular wiper device

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.
