To provide a method by which intrusion noises from a door tail of a sliding door are reduced.SOLUTION: A sliding door device 40 provided in an opening 34h of a railway vehicle 20 comprises: sliding door rails 42 and 44 provided in the opening 34h; a sliding door 50 that moves along the sliding door rails 42 and 44 between a closed position to close the opening 34h and an open position to open the opening 34h; and an elastic encapsulation part 60 having deformation promotion parts 66 and 68 in which longitudinal hollow parts 67 and 69 are formed. When the sliding door 50 moves from the open position to the closed position along the sliding door rails 42 and 44, the deformation promotion parts 66 and 68 deform so that the elastic encapsulation part closes a clearance between a door tail side edge of the sliding door 50 and a vehicle body 30 of the railway vehicle 20 in a state in which the sliding door 50 is positioned at the closed position.SELECTED DRAWING: Figure 2
