CONSTITUTION:A rail part 1 for hanging and holding a door 16 by means of a hanger roller 17 and a base part 2 for installing various parts of an automatic door device are separately formed. The rail part 1 is horizontally fixed to a flat bar 6 etc., by means of bolts 8. A rail side recessed groove shape 3 such as a projected letter-like cross section is formed on the rail side upper horizontal plate part 1b of the rail part 1 in the length direction. A connecting bolt 10 is unremovably locked and engaged with the rail side recessed groove shape. The base side lower horizontal plate part 2b of the base part 2 is superimposed on the rail side upper horizontal plate part 1b. The connecting bolt 10 is penetrated through a bolt penetrating hole 9 punched in the base side lower horizontal plate part 2b. A nut 15 is screwed and fastened to its head part to fix the base part 2 on the rail part 1. |
