ニット。In a wiper device in which a reciprocating sliding motion is linked to a wiper blade from a drive unit containing a motor, a reduction mechanism, and a conversion mechanism via a rotation shaft, the free end of the wiper rotation shaft and the drive shaft of the drive unit are connected to each other. The free end of the coil spring is inserted into a single coil spring, and both ends of the coil spring are respectively engaged with the outer periphery of the rotation shaft and the outer periphery of the drive shaft to form a rotation mechanism. A wiper drive unit is characterized in that the wiper drive unit is configured such that it exerts a safe buffering effect against unexpected external forces.
