Abstract:
There is provided an urging mechanism that elastically urges a second end portion of a worm shaft that is supported so as to be pivotable about a first end portion. The urging mechanism is configured to adjust a backlash between the worm shaft and a worm wheel by elastically urging the second end portion in a perpendicular direction that is perpendicular to a direction in which an inter-axis distance between the worm shaft and the worm wheel increases and decreases, in a state where increases and decreases in the inter-axis distance is prevented.
