A cockpit door body 10 can be opened toward a cockpit in a direction shown by arrow R<SUB>1 </SUB>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 </SUB>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 </SUB>by the difference in pressure between the cockpit and cabin to thereby reduce pressure difference.
