Apparatus for transferring a substrate and apparatus for treating the substrate including the same

A substrate transferring apparatus and a substrate treating apparatus by including the same are provided to drive upper and lower rollers simultaneously and to include a rotation power transmission member for rotating a second transfer unit according to rotation of a first transfer unit. The first transfer unit(105) includes the first rotation shaft(110) mounted rotatably. The first transfer roller(120) is combined with the first rotation shaft and supports the first surface of a flat type substrate. The second transfer unit includes the second rotation shaft mounted in parallel to the first rotation shaft by interposing the substrate. The second rotation shaft is rotated according to the rotation of the first rotation shaft. The second transfer roller is combined with the second rotation shaft and supports the second surface corresponding to the first surface. The first magnetic is alternately formed on the first transfer roller and have the opposite polarities. The second magnetic is alternately formed on the second transfer roller, correspond to polarities of the first magnetic and have the opposite polarities.
