The invention provides a sliding door supporting device capable of suppressing lateral sliding of a load roller for supporting the self-weight of a sliding door. An upper guide unit (70) of a slidingdoor support device (20) is provided with: a first upper guide roller (73) and a second upper guide roller (74) that move along an upper rail (30); an upper load roller (75) that rolls on a rolling surface extending along the upper rail (30); and an upper rotating arm (72), the base end of which is rotatably connected to the sliding door (13), and which supports the first upper guide roller (73),the second upper guide roller (74), and the upper load roller (75) at a position closer to the tip than the base end.

    本发明提供一种能够抑制支承滑动门的自重的负载辊横向滑动的滑动门支承装置。滑动门支承装置(20)的上侧引导单元(70)具有:第一上侧引导辊(73)以及第二上侧引导辊(74),该第一上侧引导辊以及第二上侧引导辊沿着上侧轨道(30)移动;上侧负载辊(75),该上侧负载辊在以沿着上侧轨道(30)的方式延伸的滚动面上滚动;以及上侧转动臂(72),该上侧转动臂的基端部以能够相对于滑动门(13)转动的方式与滑动门(13)连结,并且该上侧转动臂在比该基端部靠近顶端的位置上支承第一上侧引导辊(73)、第二上侧引导辊(74)以及上侧负载辊(75)。
