PROBLEM TO BE SOLVED: To easily open a part of a door in the inspection work with respect to a storage box for storing an oxygen mask for passenger of an airplane. SOLUTION: This oxygen mask storing box comprises a housing 10 closed by the door 12, and a piping accommodated in the housing for supplying a breathing gas through a soft tube by the first pressure. In an ordinary condition, the door 12 is held on a close position by hooks 14, 16. The hooks can be unhooked in need of touch with the mask. The opening of the door is limited to a partially opened state by transmitting an electric signal, or changing the pressure in the piping to the second pressure to prevent the dropping of the mask in unhooking.
