To provide a nasal pressure balancing device for an underwater mask.SOLUTION: A nasal pressure balancing device for an underwater mask includes two pockets. Each pocket has an opening and a bottom area corresponding to the opening. Each bottom area is pre-formed to have a first shape with multiple continuous bending sections and is located in a first position away from the nose wings of a user. Each bottom area is stretched and transformed into a second shape, and can exist in a second position close to the opposing nasal wings of the user when each of user's two fingers applies force to a bottom area toward the inside from the openings of the two pockets. Each bottom area restores automatically or returns to the first position under the outward pressing force and can return to the first shape when the applied force is released.SELECTED DRAWING: Figure 1A

    【課題】水中マスク用の鼻部圧平衡装置を提供する。【解決手段】水中マスク用の鼻部圧平衡装置は2つのポケットを含む。各ポケットは、開口と、開口に対応する底部領域を有する。各底部領域は、複数の連続する屈曲部を有する第1形状をなすように予め成形されるとともに、使用者の鼻翼から離れた第1位置に存在する。使用者の2本の指が、それぞれ、2つのポケットの開口から内側に向かって底部領域に力を加えたとき、各底部領域は、伸ばされて第2形状に変形し、且つ、使用者の対向する鼻翼に近接する第2位置に存在可能となる。加えられた力が解除されると、各底部領域は自動的に復元するか、外側への押力を受けて第1位置まで復帰し、第1形状に戻り得る。【選択図】図1A
