A device for lifting a variable valve for a vehicle comprises a drive cam(51), a roller guide(52), a connecting roller(53), and a return spring(55). A center shaft of the drive cam is eccentrically installed. The roller guide which has a curvature(52b) is rotated with the drive cam by a hinge pin. The connecting roller vertically moves along the curvature of the roller guide by the drive cam. The roller guide has a tappet(54) at the lower end. One end of the return spring elastically supports the connecting roller to return the connecting roller to its original location. The center part of the return spring is hinged by a fixing pin(55a). The tappet is connected with the connecting roller by a hinge shaft.
