Abstract

Selon la présente invention, une partie de réglage est disposée sur les deux côtés inférieurs de la surface externe d'un masque, et des parties de traction sont formées au moyen d'un côté de chaque bande d'oreille traversant une partie de réglage correspondante dans la direction horizontale et, lorsque les bandes d'oreille, dont les longueurs ont été réglées par les parties de traction, sont enroulées autour des oreilles d'un utilisateur, les bandes d'oreille et les parties de traction sont pliées à 180 degrés au moyen des parties de réglage, permettant ainsi à l'état réglé en longueur des bandes d'oreille d'être maintenu de manière stable, et ainsi le masque adhère fermement et étroitement à la zone faciale de l'utilisateur et, par conséquent, en maintenant l'état dans lequel le masque adhère de manière stable et étroite à la zone faciale de l'utilisateur, un bénéfice peut être obtenu par filtrage uniforme de substances nocives dans l'air extérieur.
