PROBLEM TO BE SOLVED: To provide a sliding door gate which is lightly and surely opened/closed by arranging a sliding door body on a road side outside a lot and arranging an erect wall inside the lot. SOLUTION: A load of the sliding door body 4 on the road side is borne by making a traveling roller 45 roll and travel on a lower rail 3 which is installed in such a manner as to be flush with a ground surface on the road side of a reinforced concrete wall 1 inside the lot. Guide rails 46 on the lot inside surfaces of the top and bottom rails 41 and 42 of the sliding door body 4 are cover-fitted to and engaged with upward horizontal rollers 26 which are installed in the upper and lower positions of the outside surface of the reinforced concrete wall 1 via a roller base 2 by a through-bolt 28, respectively. Thus, the sliding door body 4 is rectilinearly opened/closed on the road side of the reinforced concrete wall 1 by securing the self-supportability of the sliding body 4.
