The present invention relates to a mask which has a newly improved structure related to a fixating method compared to a conventional fixating method so as to actively prevent a mask from slipping down due to over-activities, and has more improved tightness by forming a shape to correspond to a face line of a user. The mask of the present invention comprises a lower end inflow hole (1) and front and rear inflow holes (2, 3) formed on a face portion (10) and a hood portion (20), respectively, to induce a fixating string (40) made of an elastic material to be coupled thereto. The fixating string (40) is divided into an upper line (41) and a lower line (42), and arranged, wherein both ends of the upper line (41) and the lower line (42) are separately taken out to a rear side of the hood portion (20) such that whether to fasten an upper side and a lower side is selectively determined by each adjusting means (60). |
