A sliding fire door is disclosed with an improved tightness of the closure by the door main body. The sliding fire door includes an opening frame, a fire door, and a guiding mechanism. The guiding mechanism includes a guide roller group which includes a plurality of guide rollers arranged one adjacent to another along the slide direction and which is configured to guide the door main body. The guiding mechanism is configured to guide the door main body such that the door main body is moved from an opening position to a closing position. The door main body has a first opposing surface which is oriented toward the wall. The opening frame has a second opposing surface which is oriented toward the first opposing surface of the door main body in the closing position. The guiding mechanism moves the door main body to cause the first opposing surface to be moved closer to the second opposing surface when the door main body is moved from the opening position to the closing position.
