Lavatory compartment structure of aircraft

A lavatory compartment structure of an aircraft comprising:

• a first lavatory compartment surrounded by a first housing;
• a second lavatory compartment adjacent to the first lavatory compartment and surrounded by a second housing;
• a movable wall that is movable between a closed position of closing a space between the first lavatory compartment and the second lavatory compartment and an open position of opening the space between the first lavatory compartment and the second lavatory compartment;
• and
• a main lock mechanism of the movable wall,
• wherein the first housing and the second housing constitute a lavatory housing,
• wherein the main lock mechanism includes:
• a first operation member that is operable from one side of either the first lavatory compartment or the second lavatory compartment;
• a second operation member that is operable from the other side of the first lavatory compartment or the second lavatory compartment;
• and
• a locking portion connected to the second operation member and that is movable between a lock position preventing movement of the movable wall with respect to the lavatory housing, and an unlock position enabling movement of the movable wall with respect to the lavatory housing,
• wherein, by operating the first operation member, the first operation member may be shifted to either an engaged state in which the first operation member is engaged to the second operation member or a separated state in which the first operation member is separated from the second operation member, and
• wherein, in the engaged state, the second operation member may not be operated to move the locking portion from the lock position to the unlock position, and in the separated state, the second operation member may be operated to move the locking portion from the lock position to the unlock position.
