Claims

[Claims for Utility Model Registration] A first gear, one end of which is rotatably eccentrically fixed to a rotating part of a wiper motor, and the other end of which is formed as a free end provided with a sector gear; a second gear that performs a swinging movement for driving the wiper by meshing with the sector gear; and a second gear that is rotatably fixed around the rotation axis of the second gear and that rotates around the center of the sector gear of the first gear. the first gear has a first convex stepped portion functioning as a washer in a region connected to the connecting member, and a second convex step portion for preventing distortion in another region. A wiper motor output gear structure characterized by being sintered and formed to have a convex stepped portion.
