The whole of the monitor device in the right-left direction overlaps a first front window when the monitor device is seen in the front-rear direction. The monitor device is disposed at a position at which the whole of the monitor device overlaps the first front window when the monitor device is seen in the front-rear direction.

A lavatory door including an ashtray is disclosed herein. The lavatory door includes a door panel having a first side and an opposing second side and the ashtray disposed within the door panel. The ashtray includes a first outer panel disposed along the first side of the door panel and configured to move away from the door panel, a second outer panel, opposite the first outer panel, disposed along the second side of the door panel and configured to move away from the door panel, and a bottom surface extending from the first outer panel to the second outer panel.

A portable scent dispensing ashtray includes an enclosure and a lid. The enclosure comprises an ash retaining portion, an absorbent retaining portion, and a dispenser retaining portion. An absorbent is retained by the absorbent retaining portion. A dispenser is retained by the dispenser retaining portion and stores odor neutralizing matter that is to be absorbed by the absorbent. The lid is rotatably attached to an upper end of the enclosure such that the lid opens or closes. When the lid opens, the ash retaining portion is exposed allowing ash or waste to be deposited into or removed from the ash retaining portion. When the lid closes, the lid activates the dispenser causing the odor neutralizing matter to be released and absorbed by the absorbent. The ashtray is portable and fits into any standard cup holder. The ashtray automatically provides odor neutralization without having to carry a separate odor neutralizing spray.
