The worm wheel is meshed with the worm gear. The worm wheel includes a first side surface, a second side surface opposite the first side surface, a peripheral edge with a plurality of teeth between the first side surface and the second side surface, and a vane on the first side surface. The vane extends radially between a center of the first side surface and the peripheral edge.
