PURPOSE: A plug door device is provided to be installed to various kinds of vehicle and reduce manufacturing and maintaining costs through simple structure and small installation space. CONSTITUTION: A plug door device comprises a feeding screw(103), a pair of sliding support units(107, 109, 124, 126, 224, 226), plugging support bars(121, 221), plugging levers(131, 231), and lever actuators(104, 105, 106, 111). The pair of sliding support unit and the plugging support bars are meshed with the both sides of the feeding screw and reciprocated along a first axial direction and a second axial direction respectively. A door is coupled with the plugging support bar coupled with the sliding support unit to be rotated. The plugging lever reciprocates the plugging levers along the second axial direction. The lever actuator rotates the plugging lever. |
