A rack structure of a dish washer is provided to maintain a fixed state of a lower rack by restricting rotation of a rack roller when the lower rack is withdrawn outside. A rack structure of a dish washer includes a lower rack. A plurality of rack rollers(126) and a rotation preventing member(200) are installed at the lower rack. The rack rollers are installed at lower ends of both sides of the lower rack, and move the lower rack back and forth. The rotation preventing member restricts rotation of the rollers. A roller supporting shaft(127) is formed at the lower ends of both sides of the lower rack, and is assembled with the rack rollers. The roller supporting shaft operates as a rotation axis of the rack rollers. A lower end of the roller supporting shaft is curved to the outside. The rack rollers are assembled to the curved lower end of the roller supporting shaft. |
