Claims

[Scope of utility model registration request]

A wiper rod is connected via a pivot joint to a crank arm that is connected to the output shaft of a wiper motor and driven to rotate, and the height of the lower inverted position of the blade connected to the wiper arm is changed by changing the reciprocating range of the wiper rod. In the wiper device for a vehicle, the pivot portion includes an eccentric bushing, a stay, a stopper, and a biasing means, and the stay is disposed between the eccentric bushing and the crank arm. A stopper is rotatably supported at the end of the stay, and a biasing means is provided between the stopper and the stay, and the stay rotates together with the eccentric bushing. ,
A wiper device for a vehicle, wherein the stay engages with the crank arm or the wiper rod by the stopper, and the eccentric bush is selectively connected to either the crank arm or the wiper rod.
