The present invention relates to a secondary rack-operated power steering apparatus. The rack-operated power steering apparatus is coupled to a rack bar by using a ball as a medium, is rotated by a drive pulley and a driven pulley connected to a driving belt, and includes a ball nut for sliding the rack bar in a housing. The rack-operated power steering apparatus includes a bearing which is mounted on the outer peripheral surface of the ball nut to support the rotation of the same; a wave washer arranged on the upper and lower sides of the bearing; and a protrusion protruding toward the bearing from the housing. Accordingly, the present invention can enhance the durability of the wave washer and bearing. |
