PURPOSE: A rail device is provided to enable a transfer rail to be continuous transferred even in a process of passing a place of different height. CONSTITUTION: Each unit(100) cuts a rail where a hanger is transferred in a regular length and a unit rail(110) is equipped with primary protrusions(111,112) in a center of height. Herein a unit channel(120) includes secondary protrusions(121,122) at both ends thereof while a side panel(130) contains a hinge(133) to combine a different unit having third protrusions(131,132) at both centers and fixed in parallel with the unit rail(110). The primary protrusions are positioned in an extended line of the hinge(133) on the side panel and primary and third protrusions provide taper sides(113,124,134) for the unit(100) to rotate within a predetermined angle upward and downward upon a mutual hinge. A guide groove(123) is formed so the unit rail(110) of different unit as to bond. Thereby, a unit is extendable to be assembled in a method of connecting the hinge to a hinge hole so a height of a hanger is adjustable.
