Abstract
A steering system includes a two-way clutch, a worm wheel that is rotatable together with an input shaft, and a coil that generates a drive force for the two-way clutch to couple/decouple the input shaft and an output shaft to/from each other. The worm wheel has a center circular plate portion fixed to the input shaft, a radial ring portion that projects forward from a peripheral edge of the center circular plate portion, and a toothed portion that projects outward in the radial direction from the radial ring portion. The two-way clutch is disposed in a space surrounded by the center circular plate portion and the radial ring portion and formed on the front side with respect to the center circular plate portion. The coil surrounds an outer peripheral surface of the radial ring portion.
