Abstract: Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction.

Abstract: A window assembly comprises a hollow frame with a trackway mounted upon each frame side including opposed pairs of inner and outer channel tracks of dovetail shape in cross section. Opposed pairs of channel slides of dovetail shape are movably mounted in opposed tracks. A window support bracket overlies each slide and adjacent its lower end is pivotally mounted thereon. Upper and lower sashes are interposed between pairs of opposed support brackets and secured thereto. The upper and lower sashes and connected channel slides are adapted for vertical adjustments along the inner and outer tracks respectively, and the upper and lower sashes and connected support brackets are adapted for selective inward pivotal movement approximately 90.degree. to facilitate cleaning.
