Claims

[Claims for Utility Model Registration] (1) A crankshaft connected to a wiper arm and an eccentric shaft eccentric to the crankshaft and rotating integrally with a drive gear are coupled and separated via an electromagnetic clutch. , in a wiper drive device configured to perform a retracting movement when the wiper is stopped by utilizing the eccentricity, a buffer member is provided between the stator and the movable element of the electromagnetic clutch; A wiper drive device characterized in that the wiper drive device is interposed so as to operate at the dead center of the wiper drive device. (2) The wiper according to claim 1 of the utility model registration, characterized in that a spring is used as the buffer member, and the spring is interposed between the armature and the pole so as to be elastically deformed. Drive device. (3) A request for registration of a utility model characterized in that a leaf spring is used as the spring, and the leaf spring is positioned at the tip of the plunger so as to be elastically deformed between the armature and the pole. The wiper drive device according to item 2.
