Hereinafter, referring to FIGS. 11 and 14 to 15, the coupling and separation of the mask frame 120 and the gap fixing unit 150 in the mask mask 100 according to the present embodiment will be described.

First, in order to couple the gap fixing portion 150 to the mask frame 120, the gap fixing portion 150 is slightly bent to narrow the gap between the insertion ends 160. In this state, the protruding end 163 of the insertion end 160 is inserted into the insertion hole 126 of the mask frame 120. At this time, in the process of inserting the protruding end portion 163 into the insertion hole 126, the fitting portion 123 of the mask frame 120 is partially inserted into the insertion slot 152 and the insertion plate fixing portion 150 is inserted. The protrusion 154 is inserted into the receiving slot 125.

The surface 166 is in contact with the first engaging surface 128 while moving along the first inclined surface 127 of the insertion hole 126. As such, the second engaging surface 166 of the insertion end 160 and the first engaging surface 128 of the insertion hole 126 come into contact with each other, and the fitting portion 123 is completely inserted into the insertion slot 152. The occupant plate fixing part 150 is firmly fixed to the mask frame 120.

Since the fixed shroud plate fixing part 150 does not fall out well unless the shroud plate fixing part 150 is bent, the gap between the shroud plate fixing part 150 and the mask frame 120 may be used. It is possible to maintain the tightness of the coupling.

And since the insertion slot 152 inserted into the fitting portion 123 is caught by the step 124 of the protruding member 122, it is possible to prevent the occupant plate fixing portion 150 from shaking left and right during use.

In order to separate the occupant plate fixing part 150 from the mask frame 120, the occlusion plate fixing part 150 may be reversed. That is, if the grasp plate holding portion 150 and slightly bent inwardly, the second catching surface 166 is separated from the first catching surface 128, the bent plate fixing portion 150 further bends the second catch The surface 166 moves out of the insertion hole 126 while moving along the first inclined surface 127. And when pulling the occupant plate fixing part 150 to the rear end insertion end 160 is completely out of the insertion hole 126 and at the same time the fitting portion 123 is removed from the insertion slot 152.
