A roller stopper is provided to make the structure ultra light by using elastic rebound force with excluding a complex function such as leaf spring protruding unit, a hanging sill, a housing, or a guide lever. In a roller stopper, a leaf spring guide unit has a leaf spring hanging projection formed on one side of a long leaf spring(18). A stroke unit moves back and forth with covering the leaf spring guide unit and has a front leaf spring curved in a half-arc form and a rear leaf spring equipped with the leaf spring hanging projection on the upside and integrally connected in a longitudinal direction. A stopper bracket is supported or fixed to move the stroke unit back and forth and provided with a leaf spring hanging sill(28) formed correspondently to the leaf spring hanging projection. A driving leaf spring(27) is kept in a half-arc form all the time to guide elastic rebound force according to the change of an area of the leaf spring or a guide bar.
