PROBLEM TO BE SOLVED: To prevent an axial load applied on a locking pin from being transmitted to a door handle in a door for an aircraft which has a lower end pivoted by a door opening and has an upper end locked by the locking pin. SOLUTION: A link mechanism 30 includes a bell crank 55 pivoted by a bracket 54 provided on a door frame 22 via a fulcrum pin 56 and swung by operation of a door handle, and a connecting rod 60 having a lower end pivoted by the bell crank 55 via a first connecting pin 61 and having an upper end pivoted by a lower end of the locking pin 28 via a second connecting pin 62. When the locking pin 28 is locked to a pin receiving member 29, the fulcrum pin 56, the first connecting pin 61, and the second connecting pin 62 are positioned on a straight line L3. Accordingly, even when a trunk is radially expanded by the difference between inside and outside air pressures and an axial frictional force is applied between the locking pin 28 and the pin receiving member 29, the axial frictional force can be transmitted from the connecting rod 60 to the door frame 22 via the bell crank 55 for support.
