Abstract
A reducer of an electric power steering apparatus is disclosed. It reduces rattle noise generated by a backlash due to friction and wear of a worm and a worm wheel or an impact transmitted from a road surface through a wheel and a steering shaft and enhances a steering feeling of a driver by improving the catching phenomenon and rotational resistance generated between a worm shaft and a worm shaft bearing.
