Claims

[Claims for Utility Model Registration] (1) A crankshaft connected to a wiper arm and an eccentric shaft eccentric to the shaft 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 using the eccentricity,
A wiper drive device characterized in that a buffer member is interposed between the stator and the movable element of the electromagnetic clutch so as to act at least at the dead center of the movable element in a demagnetizing state. (2) A practical application characterized in that a cushion member is used as the buffer member, and the cushion member is attached to a mounting member fixed to the tip of the plunger so as to contact the member on the stator side. A wiper drive device according to claim 1. (3) A cushion member is used as a buffer member, and the cushion member is attached to a mounting member protruding from the yoke so as to contact the armature. The wiper drive device according to item 1.
