Title: Cockpit door of aircraft

Abstract: A cockpit door body 10 can be opened toward a cockpit in a direction shown by arrow R.sub.1 by a crew inside a cockpit 3 by manipulating a knob on a first hinge device 40. When rapid decompression occurs in the cockpit, a mechanical pressure-sensitive device of the first hinge device 40 operates to release a bolt from a catch. By the difference in pressure between the cabin and the cockpit, the door body 10 opens in the direction of arrow R.sub.1 to thereby reduce pressure difference. When rapid decompression occurs in cabin 4, a second latch device 60 detects this pressure difference and operates mechanically to rotate a link lever 62 to release a stopper 64 from a catch 66. Flaps 30 and 32 are opened toward cabin 4 in the direction of arrow R.sub.2 by the difference in pressure between the cockpit and cabin to thereby reduce pressure difference.
