PROBLEM TO BE SOLVED: To provide a suspended extensible door which facilitates canceling operation of a rail lock means after contraction of an extensible door body to a hanging side, and achieves automatic locking of a rotary rail at a connection location upon engagement of a hook with a receptacle when the rotary rail is rotated to the connection location. SOLUTION: According to the structure of the suspended extensible door, the rail lock means 10 for locking the rotary rail 7 to a fixed rail 6 of a guide rail 3, at the connection location A, is arranged above a movable-side end frame 17 of the extensible door body 4 in a contracted state, and an operating rod 27 for canceling the rail lock means 10 by upward operation at the connection location A is arranged on the movable-side end frame 17 in a vertically movable manner. The rail lock means 10 is formed of the receptacle 35 which is arranged on one of the rotary rail 7 and the fixed rail 6, and the hook 38 which is guided in an engaging direction due to rotating motion of the rotary rail 7 when the rotary rail 7 is rotated from a rotationally stored location B to the connection location A with the operating rod 27 kept in a lowered state, and engages with the receptacle 35.
