Claims

[Claim for Utility Model Registration] In a fully concealed wiper in which the wiper blade is driven by a wiper motor via a link and reciprocates on the windshield, the wiper blade can be moved to a storage position under the hood surface. A cylindrical eccentric bushing that passes through the output shaft of the wiper motor at an offset position, a lever that is rotatably provided on the circumference of the eccentric bushing, and a lever that is fixed to the output shaft of the wiper motor and rotates with the rotation of the output shaft. a first crank arm that connects a rotating end of the first crank arm and a rotating end of the lever so as to be relatively movable, and a connecting member that connects a link connected to the wiper arm at a connecting portion with the lever. A fully concealed wiper drive device, comprising: a second crank arm that rotates with the wiper motor; and engagement means that selectively engages the eccentric bushing with the fixed member or the lever that does not rotate with the output shaft of the wiper motor.
