One object is to provide a plug door device that can make a contribution to a size reduction thereof, while suppressing a decrease in airtightness of a door. A plug door device is provided with an electric motor, a plug operation portion that moves a door in a width direction of a vehicle, a front-back operation portion that moves the door in a front-back direction of the vehicle, a movement suppressing portion that can suppress movement of the door in the front-back direction, and a planetary gear mechanism that distributes a drive force of the electric motor to the plug operation portion when movement of the door in the front-back direction is suppressed by the movement suppressing portion, and distributes a drive force of the electric motor to the front-back operation portion when movement of the door in the front-back direction is not suppressed by the movement suppressing portion.

A plug door opening-closing apparatus includes a lock mechanism, a drive mechanism, and a door support mechanism. The lock mechanism is directly or indirectly arranged on one of the upper and lower portions of at least one door of a vehicle. The lock mechanism locks the door when completely closed so that the door does not open. The drive mechanism is coupled to the lock mechanism and drives the lock mechanism to switch the door from an unlocked state to a locked state. The door support mechanism is mechanically coupled to the lock mechanism and supports the door. When the completely closed door is switched from the unlocked state to the locked state, the door support mechanism is adapted to hold the door and hinder outward displacement, in a vehicle width direction, of the other portion of the door where the lock mechanism is not arranged.

An opening formed in a window glass pane is smoothly opened and closed by a slide panel slidingly driven along a panel surface of the window glass pane and along a direction orthogonal to the panel surface. The guide rail (4) is provided with a pin guide groove (27) including a groove main portion (27a) and a groove extension portion (27b). A slider (20) is provided with a pin drive groove (30) extending in a direction crossing the panel surface. The slide panel is provided with at least one pin (16) projecting into the pin drive groove and the pin guide groove so that the slide panel is positioned in a closed position when the pin is positioned in the groove extension portion, and in an open position when the pin is positioned in the groove main portion.
