Abstract:
A wiper device comprising a drive shaft that reciprocates pivotally, a wiper arm fixed to the drive shaft and reciprocating together with the drive shaft, and a wiper blade connected to the wiper arm by a connecting portion that moves with the reciprocating pivotal movement of the wiper arm to wipe a surface to be wiped, at least one portion of the wiper arm being positioned above the wiper blade in an overlapping manner in relation to said surface to be wiped, said wiper device further comprising:vibration limiting means that is pivotably provided in one of the wiper blade and the wiper arm so that relative vibration can be limited alternatively with respect to the other of the wiper blade and the wiper arm at a position other than the portion where the wiper blade and the wiper arm are connected in a range where the wiper blade and the wiper arm overlap with each other and that limits, within a predetermined clearance range, relative vibration of the wiper arm and the wiper blade during the reciprocating pivotal movement.
