PROBLEM TO BE SOLVED: To reduce a depth width of the whole lower rail by constituting a lower rail main body by connecting an inside member and an outside member to each other through heat insulating connecting materials, and constituting so as to arrange a heat insulating reinforcing material where the engaging groove one end of a sash roller arranged on the under side of the heat insulating connecting materials of the lower rail main body is installed on the inside member and the other one end is installed on the outside member. SOLUTION: An inside member 1a composed of an aluminum extruded section and similarly an outside member 1b, are connected to each other through heat insulating connecting materials 2 and 2, and an engaging groove 4 of a glass panel 3 is arranged just above the heat insulating connecting materials 2 of a lower rail main body 1, and an engaging groove 6 of a sash roller 5 is arranged just under it. Sandwiching inserting grooves 10 and 10' of an under surface side opening are also formed on an inside surface on the lower side of part pieces 9 and 9' of the inside member 1a and the outside member 1b, and locking part pieces 11 and 11' are sandwiched and inserted in the sandwiching and inserting grooves 10 and 10', and heat insulating reinforcing materials 13 are arranged between members 1a and 1b. Therefore, a lower rail device by which a depth dimension can be reduced more than a conventional example and which has no hindrance to strength by using a reinforcing member, can be provided.
