PROBLEM TO BE SOLVED: To provide a structure for preventing a top-railed sliding door from coming off, which can effectively prevent the sliding door from coming off from an upper rail, even when the sliding door moves in a horizontal direction or swings forward/backward.SOLUTION: A structure for preventing a top-railed sliding door from coming off includes an upper rail 20, the top-railed sliding door 10 in which a roller member 11 travelable along the upper rail 20 is attached to an upper part, and a cover member 30 that is attached to a position to face the upper rail 20. The cover member 30 regulates the horizontal and vertical movements of the sliding door 10, and regulates inclination of the sliding door 10 so as not to become an angle larger than a predetermined angle, when the sliding door 10 swings. |
