PROBLEM TO BE SOLVED: To materialize a mounting structure of an upper rail member which excels in mounting workability and surely prevents rattling movements of the upper rail member mounted on a base member fixed to an upper frame, being a mounting frame of an automatic door. SOLUTION: A mounting plate part 8 of an upper rail member 3 is inserted into an engaging/fitting linear recessed groove 13 of a base member 5 fixed to the upper frame, being the mounting frame of the automatic door, through an opening part 14. An upper engaging/abutting part 11 and a lower engaging/abutting part 12 are loosely engaged with an upper engaging/fitting part 15 and a lower engaging/fitting part 16, respectively. Then, a fixing screw 9, threadingly fitted to a fixing screw hole 10 and penetrating to the side of the base member 5, is threadingly fitted to a groove part 18 while destroying a longitudinal directional part of each of the linear projections of the groove part 18, and is advanced and pressed in a threading manner with the front end face of the screw abutting on a bottom part 18a of the groove part 18. Thus, the upper engaging/abutting part 11 and the lower engaging/abutting part 12 are engaged under pressure with the upper engaging/fitting part 15 and the lower engaging/fitting part 16, respectively.
