Document Type and Number:
WIPO Patent Application WO/2018/079248
Kind Code:
A1
Abstract:
Provided is a vehicular wiper device equipped with: a first motor which, by rotation of a first output shaft, causes a wiper blade connected to the leading end of a wiper arm to perform a wiping action between two different reversal positions on a windshield; a second motor which, by rotation of a second output shaft in synchronization with the rotation of the first motor, actuates an extending/contracting mechanism provided to the wiper arm so as to allow the wiping range of the wiper blade on the windshield to vary; and a control unit which controls the first and second motors such that the wiping range along the outward path is smaller than the wiping range along the return path.
