The oxygen mask is put on by fitting. Therefore, the wearing band does not hit the ears or eyes, and the wearer does not feel uncomfortable. When the wearing band is worn so that the middle part between both ends is located at the lower part of the back of the head or the upper part of the neck of the mask wearer, the wearing band does not easily hit the pillow or the like in the sleeping state and is not easily displaced.

In order to make it difficult for the oxygen mask portion to be displaced when the oxygen mask portion is attached to the face, it is desirable to form the attachment band itself or a part thereof with a stretchable cloth or the like. Examples of the stretchable cloth include a cloth woven with rubber thread and a cloth made of polyurethane elastic thread. If the mounting band is made of a cloth that cannot be stretched, connect a rubber cord or a stretchable cloth to both ends of the wearing band, and attach a hook-and-loop fastener piece to the tip of the rubber strap or the stretchable cloth. It is desirable to do.

For accurate wearing of the oxygen mask, the wearing band and the hook-and-loop fastener piece of the mask part are marked with a mark or color that can distinguish the upper and lower sides so that the wearing band is not accidentally attached to the mask part. It is desirable to keep it. For example, the surface fastener piece on the upper side of the wearing band or the mask portion may be blue, and the surface fastener piece on the lower side or the bottom surface of the wearing band or mask portion may be white.
