Abstract: Provided is an aircraft lavatory unit that advantageously allows for a reduced number of parts, simplified assembly, and reduced costs while ensuring convenience. First and second lavatories are provided adjacent to one another within a structural frame. Respective sinks of the lavatories are disposed by being attached to the partition wall. A trash insertion port is provided on a wall surface of each base. A single storage chamber provided within the bases of the sinks of the lavatories extends into the bases of the sinks of the lavatories through an opening provided in the partition wall. A trash can device has a single trash can housed in the storage chamber and a single fire extinguisher. A water heater is singularly provided, which is disposed within the base of one of the sinks.

Abstract: Coil springs are incorporated, with a longitudinal direction oriented vertically, into the top and bottom end parts of hinge pieces provided on side surfaces of opposing door panels of a folding door and that connect the doors panels together. A portion of a pin plate is inserted into the coil springs at the top and bottom end parts of the coil springs and attached to the coil springs. The pin plate that is inserted into the top end part of the coil spring incorporated into the top end part of the hinge piece and the pin plate that is inserted into the bottom end part of the coil spring incorporated into the bottom end part of the hinge piece are fixed to the hinge pieces by brackets. The folding door is closed by the restoring force generated by the twisting of the coil springs.
