The invention provides an externally suspended side sliding door device of a railway vehicle, having improved the reliability of a door suspension device supporting side sliding doors in suspended manner and moving in rolling motion along an upper door rail for guiding side sliding doors, and facilitated the maintenance operation thereof. A weather strip member (200a) is disposed at a lower end portion of an external cover (22) on the side facing a side sliding door (100a), and a weather strip member (210a) is disposed at an upper end portion of the side sliding door (100a) on the side of the external cover (22) opposing to the weather strip member (200a). The weather strip members (200a,210a) are integrated when the side sliding door is closed, sealing the gap formed between the lower end portion of the external cover (22) and the upper end portion of the side sliding door, thereby enhancing the water-resisting property and the dust-resisting property of the upper door rail (130) and the door suspension device (140) moving in rolling motion on the upper door rail (130) and supporting the side sliding door in a suspended manner. The side sliding door is guided along a groove-shaped lower door rail embedded in a door step via a tongue portion suspended from a lower portion of the side sliding door. |
