ABSTRACT:
A wiper device for a vehicle which, when abnormal load is applied, absorbs the abnormal load so that wiping operation by a wiper blade can be carried out continuously. The wiper device is compact, and dimensional management thereof is easy. One end of a first crank lever forming a portion of a crank arm is attached to an output shaft, whereas a cylindrical portion is fixed by caulking to another end of the first crank lever by a pin. An annular portion is formed at one end of a second crank lever. An elastic rubber bush is interposed between the cylindrical portion and the annular portion. The first crank lever and the second crank lever are supported by the elastic rubber bush so as to be freely rotatable.
