The present invention relates to a rail device capable of adjusting a height of a hanger and preventing a fall of a foreign object. First and second units (200, 200) each including a unit rail are extended and coupled continuously and repeatedly so as to be adjusted in a height of a hinge (233). The first and second units (200, 200) each includes a unit rail (210) dividing a rail on which a hanger is transferred to have a predetermined length and having first protrusions (211, 212) in a central portion of a height in a length direction; first and second unit channels (220, 220) having a length perpendicular to a direction in which each unit rail (210) is transferred, fixed to each unit rail (210), and having second protrusions (221, 222) on both sides of vertical plates (225) at both ends; and side plates (230) fixed to corresponding vertical plates (225) at both ends of the unit channels (220, 220) in parallel, having third protrusions (231, 232) at the centers of both sides, and having hinges (233) coupled to extend in a length direction of the unit rail (210) to form adjacent first and second units (200, 200), and further comprises: a first channel support (260) and a second channel support (270) each coupled to the corresponding side plates (230) coupled to the first unit channel (220) and the second unit channel (220), having different planar surfaces and overlapping longitudinal end portions on lower surfaces of the first unit channel (220) and the second unit channel (220), and simultaneously covering transverse corners of the unit rail (210), the vertical plates (225), and lower surfaces of the side plates (230). |
