Claims (1)

[Scope of utility model registration request] Attach a pair of hangers to the top of the sliding door, place the end runner on one hanger and the middle runner on the other hanger at different levels, and place the lower side of the higher runner on the lower side of the sliding door. A spacer with a smaller diameter than the runner is provided, and a lower flange with a larger diameter than the small diameter spacer is provided on the lower surface of the small diameter spacer, parallel to the end and middle of the moving rail for opening and closing the sliding door. A pair of closing rails are extended to close the sliding door, and the end runner is delivered to the end closing rail, and a middle runner is delivered to the middle closing rail. Then, the lower surface of the lower runner and the lower surface of the lower flanges provided below the higher runner are movably placed on the upper surface of the rail, and the sliding door is suspended, allowing the end runner to pass through without contact. A fixed guide body is installed on the branch side of the middle closing rail to guide only the middle runner on the guide surface and switch the course between the moving rail and the middle closing rail. A structure for switching the direction of the sliding door runner, which is provided at the same height as the middle runner at the base end.
