In a changeover system of the present invention, the upper part of the transverse pushing action section of the article transverse pushing body is formed as a tilted upper surface with a middle portion in the front rear direction being tilted forward and downward and a front end portion is formed as a leading end upper surface with gradual inclination conjointly with the tilted upper surface. As a result, the leading end upper surface with gradual inclination smoothly enters below the article, the article can be lifted by the tilted upper surface, and the prescribed transverse movement can be implemented without squeezing the article.
