Abstract
By reducing thickness of a slidable contact member which is attached to an output shaft and a sector gear part and slidably contacts with a gear case, a wiper motor is downsized. A motive power conversion member comprises: an arm part rotatably connected to the worm wheel; and a sector gear part meshing with the output gear, wherein a gear shaft of the sector gear part is swingably supported with respect to the output shaft by a swinging plate. A first slidable contact member is mounted on a tip of the output shaft, and a second slidable contact part which is formed separately from the first slidable contact member is attached to a tip of the gear shaft, wherein the first slidable contact member and the second slidable contact part slidably contact with a cover of the gear case.
