Accordingly, the wearer performs work while moving through the sight window 22 while ensuring the field of view while breathing through the respiratory apparatus 30. However, as shown in FIG. 1, the mask of the prior art shields only the front side of the face portion 20 so that the sight window 22 can be transparently viewed, which has a problem of securing the field of view.

Specifically, the operator has only a front view through the sight window 22, but can not secure a view of the lower part.

Such a problem poses a risk to the operator in the case of a staircase or an obstacle, and in particular, it is more dangerous and troublesome when the view is difficult to obtain due to smoke such as a fire scene. Here, the mask of the prior art has a problem in that the transparent window 22 is formed to be wide and a certain view of the lower is secured, but the lower window is refracted because the transparent window 22 is formed with the same curvature.
