PROBLEM TO BE SOLVED: To solve such problems that a repulsive force is strong in a conventional nose piece, even if trying to form as a facial form after mounting it, the nose piece is bent strongly partially or becomes shallow in bending and may not respond to facial subtle irregularities, and thereby a gap is often made, and also the nose piece is easily broken to an acute angle even if trying to fix the form so as to be fit by hands before wearing it on a face, resulting in taking time to make a delicate facial line and making it difficult to achieve correct wearing without the gap.SOLUTION: By forming a nose piece in a wave shape, easily bendable portions are increased, and thereby the nose piece becomes to be bent to the mounting part spontaneously, when controlled by hands after wearing a mask. As a result, the form can be fixed with a small force, and the wearing in a short time becomes possible, and thereby it becomes easy to reduce a gap between a face and the mask. |
